1 Introduction

The Global LTE IoT Starter Kit is a next-generation System-on-Module IoT solution, enabling the design

of cellular connected edge devices, for operation in Europe.

Powered by AT&T IoT services available through Avnet, this kit provides a complete development

environment for sensor-to-cloud applications and services.

Designed to be used for both prototyping and production, the slim form-factor LTE System Board with it’s regional certifications and pre-registered Micro-SIM card for AT&T M2X service (included in the kit), as well as versatile expansion options, together provide a high level of enablement that facilitates easy IoT

deployment and reduction in overall risk.

The Starter Kit features a small (79.5 mm x 30 mm) LTE System Board built around a Wistron NeWeb (WNC) M18QWG global LTE Cat-4 modem module. The M18QWG module provides cellular modem functionality plus an applications processor core dedicated for user applications, eliminating the need for an external host processor. A rich set of embedded system peripherals, controllable through the user’s application code, are easily accessible via a 60-pin expansion connector and 2x6 peripheral module header. This enables easy system customization with application specific sensors and I/O interfaces through the addition of user-created or off-the-shelf plug-in boards. The LTE System Board includes

ambient light, temperature and accelerometer sensors onboard, for out-of-box demonstration examples.

2.1.4 Expansion Interfaces for System-Level Prototyping

Two interfaces facilitate the adding of custom hardware to the LTE System board:

System expansion interface (1.8V I/O) is a 60 pin expansion connector (Samtec ERF8 /

ERM8 series) on the underside of the system board. WNC module peripherals are accessible via this interface at 1.8V signalling levels, if 3.3V (or 2.5V) levels are required by the user’s

custom circuitry, then voltage translator devices must be added to the user’s board.

Pmod™-compatible interface (3.3V I/O) is 6x2 pin connector facilitates an easy to use

interface via I2C or SPI peripherals, for access to a wide range of Pmod™ peripheral boards. The relaxed pitch of this connector and low pin count of these interfaces also permits wiring-in other 3.3V expansion boards (eg. MikroElektronika Click modules or Grove sensor boards) for

prototyping system-level solutions

3 LTE System Board Functional Description

The following sections describe the key functional blocks on the AT&T LTE IoT System Board

3.1 LTE Modem Module (WNC M18QWG) The M18QWG is a SoC modem module from Wistron NeWeb Corporation (WNC) that provides Cat.4 LTE cellular wireless connectivity plus GNSS location tracking, as well as a full-featured application processor subsystem with peripheral interfaces and functions uniquely designed to

address the power/performance/cost constraints of IoT and M2M applications.

The quad-core ARM Cortex A7 applications processor on this module is based on Qualcomm’s MDM9207 architecture and offers (OFDMA-related) software based signal processing capabilities

that significantly exceeds the efficiency of traditional ARM based communications processors.

Host mode: The WNC module will normally operate in “host mode”, where one of the ARM

Cortex A7 cores in the on-module Qualcomm MDM device is reserved for use as the system

processor for user applications. (The other three A7 cores are dedicated to the modem functions).

Modem mode: WNC module operation in “slave mode” (as a peripheral to an external processor

interfaced to the WNC module via USB interface) is not currently supported

The M18QWG also provides system peripheral interfaces and library support for these,

(eg. USB 2.0, I2C, SPI, SGMII, PCM, HSIC, UIM, UART*, SDIO*)

Refer to the next section pinout listing of the 60 pin Expansion Connector (Samtec ERF8) for

detail regarding the M18QWG module I/O that is accessible to the User

Documentation for the M18Q2 series WNC North America module that shares similar functionality

is available at the FCC certification website https://fccid.io/NKRM18Q2

3.2 Expansion Connector

The peripheral interfaces of the WNC M18QWG module are made available to the developer for

custom system design via the board’s 60 pin Expansion Connector.

This is interface is implemented using a 2x30 pin, 0.8mm pitch, Samtec ERF8 series connector, providing a robust, space-efficient and economical stacking solution that is especially attractive for

cases where small overall physical size of the final product is vital.

Figure 7 – 3D View of Samtec ERF8 / ERM8 Connector Pair

The matching Samtec ERM8 connector that is fitted to the custom end product PCB, is made available in three different stacking heights, to better accommodate height clearance requirements

of your custom hardware. These offer 7mm, 10mm or 14mm overall clearance between the boards

3.3 2x6 Pin Peripheral Connector

The 2x6 Pin Peripheral Connector is compatible with a subset of Pmod™ peripheral boards from

Digilent, Maxim, Measurement Specialties (TE Connectivity) and others.

The pinout of this 2x6 pin right-angle socket connector is derived from the I/O signal assignments

defined in the Digilent Pmod™ Interface Specification for SPI and I2C serial interfaces.

Note however, that dual-row I2C Pmod peripheral boards in many cases may not be fitted to this board, as their duplicate SCL and SDA pins are not accommodated by the combo SPI plus I2C

interface pinout assignments implemented on the LTE System board.

3.4.3 UART1 Interface

The WNC module firmware limits UART1 to a predefined system function specifically for: “High Speed Data Transfer”

WNC UART1 modem interface as implemented via the USB Compound Device, is available through either:

the MicroUSB connector, or

the 60-pin Expansion connector

As tabled on the previous page, additional UARTs (in service of the other processor cores) also communicate over the same USB interface

3.4.4 UART2 – Software Debug UART Interface (3-pin header)

WNC UART2 is limited by the module firmware to performing the predefined system function of: “Software Debug UART”

The I/O levels of this UART are level-shifted, with it’s TX, RX and GND signals made available on a 3-pin header (J9) to facilitate external connection to a 3rd-party USB-to-Serial debug cable

Table 8 – Software Debug UART Header (J9)

J9 Pin Signal Name Description

1 UART2_TX_3V3 Level-shifted WNC UART2_TX output

2 UART2_RX_3V3 Level-shifted WNC UART2_RX input

3 GND Ground

3.4.5 Voltage Level Translation (1.8V / 3.3V)

SPI1 and UART2 interfaces plus two GPIOs (GPIO93 and GPIO95) from the WNC module are

level-shifted to 3.3V levels by Fairchild FXLA108BQX octal bi-directional level-translator device

In addition, the I2C peripheral interface bus from the WNC module is also level-shifted, using

an FXMA2102L8X 2-bit level-translator that is compatible for use with open-collector outputs

The level-shifted 3.3V signals are routed to the following connectors:

the Pmod-compatible 2x6 peripheral connector (J8) and

the Software Debug UART 3-pin header connector (J9)

3.4.6 ADC / Ambient Light Sensor (JP2)

A single ADC input is provided on the WNC module.

This inputs to a 16 bit convertor, sampled at 2.4MHz for an ENOB of 15 bits

Analog Input Bandwidth is 100 kHz (typical)

The ADC’s input range is 0.1V to 1.7V

A shorting link across jumper JP2 connects one of the following sources to this ADC input:

Table 9 – ADC Input Source Selector (JP2)

Note! Two issues should be noted that limit the utility of the ADC input on the initial production boards:

a) ADC input source selection via JP2 is not possible unless the R50 “default” resistor is removed

b) The ADC’s input voltage limit could be exceeded if the Ambient Light Sensor is exposed to an excessively bright light source, resulting in potential damage to the module. To prevent this, it is recommended that light-levels must be restricted using some form of optical filter placed over the U3 light sensor (see U3 location below)

JP2 Pins Signal Source for ADC Input

1 & 2 (default) Ambient Light Sensor output (U3)

2 & 3 Expansion Connector (J1 pin 4) (ie. driven by an external circuit)

3.4.7 3D Accelerometer Sensor (LIS2DW12)

The LIS2DW12 is a 2017-released, ultra low-power, MEMS 3-axis smart accelerometer from

ST Micro. It has 16-bit output and can be configured (with 5 settings in either mode) to prioritize:

ultra-low power consumption (< 1 µA @ ODR = 12.5 Hz), or

very low-noise performance (down to 90 µg/√Hz)

Other features include:

Selectable acceleration full-scale range of ±2/±4/±8/±16 g

32-level embedded FIFO (for measurement buffering)

Thermal stability over the full -40 to +85 °C industrial temperature range

Embedded temperature sensor

1.8V operation and I/O levels

50 nA power-down mode

Dedicated internal engine for motion and acceleration processing:

o Free-fall wakeup o 6D/4D orientation o Tap and double-tap recognition o Activity/inactivity recognition o Portrait/landscape detection

The LIS2DW12 is used as a slave device (address=0011001 b7) on the WNC module’s I2C

peripheral bus. The SA0 input of the LIS2DW12 device is tied high, but this signal is pinned-out to test-point SA0 to facilitate potential modification of (LSB) of the device I2C address

Table 10 – LIS2DW12 Interrupt Outputs

LIS2DW12 Pin Name WNC Pin Name Isolating Resistor

INT1 GPIO06 R48

INT2 GPIO07 R49

Both interrupt outputs are by default connected to the WNC module (GPIO06 and GPIO07)

If one or both of these WNC GPIOs are required for a different purpose, they may be disconnected from the LIS2DW12 device by removing resistors R48 and R49

3.4.8 Pushbutton Switches (Reset, User, Boot)

Three pushbutton switches connected to inputs on the WNC module, are mounted on the most

mechanically secure section of the board (ie. pressing down on the 60-way expansion connector)

Table 11 – Pushbutton Switch Functions

Switch # Name Switch Function How Activated

SW1 RESET WNC module Reset input Press and hold for > 3 seconds to Reset

SW2 USER User-defined trigger input User defined function, forces a logic Low on GPIO98

SW3 BOOT Force USB Boot Press + hold during reset, forces reprogramming of firmware from USB (Note! This is an advanced function that requires use of WNC_Dloader software)

3.4.9 LED Status Indicators (Power, WWAN, User)

Three LEDs are visible on the LTE System board, their functions are tabled below:

Table 12 – LED Indicator Functions

LED # Name LED Function How Activated

LED1 POWER 3V8 Power Good Indicator Illuminates if board is powered

LED2 WWAN Network Connection Status Controlled by User software: Indicates valid network connection

LED3 USER User defined RGB output Controlled by User software: User defined color and sequence

3.4.10 PCM / I2S Digital Audio Interface

PCM and I2S share the same four pins on the M18QWG module.

ie. The Digital Audio interface pins can be configured for PCM or I2S functionality.

These four pins can alternatively serve as user-defined GPIO, see table below…

Access to these signals is via the 60-pin Expansion Connector

Note: Software support for the Digital Audio Interface is not currentltly included in the SDK

3.4.11 Ethernet SGMII Interface

An SGMII interfaced Ethernet MAC is integrated within the WNC module.

This has the following key features

IEEE 802.3 compliance

Full duplex at 1 Gbps

Half/full duplex for 10/100 Mbps

Supports VLAN tagging

Supports IEEE 1588, Precision Time Protocol (PTP)

3.5 Power Regulation

Table 16 – Summary of LTE System Board Voltages

3.5.1 VIN Unregulated DC input power (in range of 4.5V to 16V) can be supplied to the LTE System board via one of three different input interfaces:

the “PWR IN” MicroUSB connector (J6)

the 60-pin Expansion Connector (J1)

the 2-pin VIN and GND aux connector (J10, unpopulated)

In the IoT Starter Kit, the provided 5V 2.5A AC/DC power adaptor applies power to the LTE

System board via the “PWR IN” MicroUSB (J6) connector

The input supply voltage can be measured by placing voltmeter test leads across the

unpopulated DC aux input connector pads (J10)

3.5.2 3V8 (VCC) 3.8V @ 3 A max, An onboard ON Semi NCP3170 buck switching regulator supplies the WNC

module’s VCC input requirement. Regulators on the WNC module then convert this voltage down to the lower core voltages required The REG_EN regulator enable input:

is pulled high following power-up via an RC delay circuit (enables the 3V8 output)

can be pulled low from the 60-pin Expansion Connector (to disable the 3V8 output)

Power Good status of the 3V8 output supply rail can be verified in two places

LED1 - illuminates green when the circuit is correctly powered and REG_EN is high

PG test point - this should be high (when circuit is powered and REG_EN = high)

An unpopulated 2-pin header site (JP1) is provided for 3V8 current measurement. To use this feature, the following board modification is required:

Zero-ohm resistor R47 must be removed

A 2-pin header connector JP1 must be added

The meter test leads must be placed across the pins of JP1

After completion of current measurements, a shorting link (JPR1) must be fitted across these JP1 header pins

Voltage Rail Voltage Current max (A)

VIN 5.0V (nominal) 1.8 A (MicroUSB) 4.0 A (Exp. Connector)

3V8 (VCC) 3.8V 3.0 A

1V8_VREF (VREF) 1.8V 0.1 A

VCC_UIM_SIM 1.8V / 3.3V 0.15 A

3V3 3.3V 0.3 A

The 3V8 module supply is filtered per WNC recommendations using the following circuit

3.5.3 1V8_VREF (VREF) 1.8V @ 100 mA max. Supplied by the VREF pin of the WNC module.

This provides 1.8V power to the following circuits:

The VREFA input of the 1.8V/3.3V level-shifter devices (U9 and U10)

The LIS2DW12 accelerometer

The LNA in the GNSS/GPS antenna circuit

Some discrete pull-up resistors

3.5.4 VCC_UIM_SIM (UIM_VCC) 1.8V or 3.0V @ 150mA max. Supplied by the UIM_VCC output pin of the WNC module

This voltage is auto set on SIM negotiation and provides 1.8V or 3.3V power to:

The “User Identity Module”, ie. the removable SIM Card.

3.5.5 3V3 3.3V @ 150 mA max. Supplied by the onboard On Semi NCP114 LDO regulator.

This supplies 3.3V power to the following circuits:

The VREFB input of the 1.8V/3.3V level-shifter devices (U9 and U10)

The Pmod Interface (J8)

3.7 WNC Module Power Control and State Interfaces

The following 6 signals fall in this category:

Table 17 – Control and State Signals

Signal Name Connected to I/O Function in this Circuit

RESET J1 pin 56 IO Allows expansion board to reset the WNC module

WAKEUP_IN J1 pin 54 I Allows expansion board to wake-up WNC module

WAKEUP_OUT J1 pin 52 O WNC module wake-up output to expansion board

REG_EN J1 pin 2 I 3V8 Regulator Enable

POWER_ON PWR testpoint I Unused, but available at “PWR” test-point

WWAN_STATE WWAN LED O Drives network status WWAN LED (Amber color) Under program control from the User application

RESET

The RESET signal on the 60-pin Expansion Connector may be used as an input or output. This functions in parallel with the onboard SW1 pushbutton switch. The WNC module is reset by a logic

low on this signal for 3 seconds or longer

WAKEUP_IN and WAKEUP_OUT

For power-sensitive applications, this mechanism allows the modem and an external host to enter

low power states whenever possible, with the other side then waking it when required.

If the modem receives data while the host is in low power state, then it must wake-up the host.

If the host needs to transmit data while the modem is in low power state, then the host must be able to wake-up the modem.

The interface consists of two signals: WAKEUP_IN is driven by an external host and received by the modem

WAKEUP_OUT is driven by the modem and received by the host.

Each side can wake the other side by toggling it’s wakeup signal high, or allowing the other side to go to sleep when not needed by toggling wakeup low.

Table 18 – WAKEUP_IN and WAKEUP_OUT

Function Driven by Signal Name

WAKEUP_IN = Low Host Host allows Modem to sleep

WAKEUP_IN = High Host Host requires the Modem, or this an ACK response to a WakeUp from the Modem

WAKEUP_OUT = Low Modem Modem allows the Host to sleep

WAKEUP_OUT = High Modem Modem requires the Host, or this an ACK response to a WakeUp from the Host

REG_EN and POWER_ON

REG_EN controls the main 3V8 regulator and is pulled high (enabled) following power-up via an

onboard RC delay circuit. This signal is also available on the 60-pin Expansion Connector for external ON/OFF control of the onboard 3V8 and 3V3 regulators. This allows system power to be

controlled by eg. a low-power MCU on the User’s custom hardware

Figure 15 – Sleep and Power Control of WNC Module

POWER_ON is the power control input to the WNC module. This is made available on a test-point

(“PWR”) but is otherwise unused in this design. (Not available on the 60-pin Expansion Connector)

Note: In the event the User application also needs control of the POWER_ON input, this requires rework of the LTE System board as R11 will need to be removed

WWAN_STATE

This signal drives the WWAN LED (Amber color) and is normally used to indicate network status,

but is control from the User application so can be repurposed if necessary

3.8 Antennas

12 Appendix A – LTE IoT Breakout Carrier The LTE IoT Breakout Carrier is an optional expansion board that facilitates system-level prototyping

using the Global LTE IoT Starter Kit

Via it’s Samtec ERM8 series 60-pin connector, a subset of the WNC LTE module’s peripheral interfaces (signaling at 1.8V levels) are level-shifted to 3.3V levels and pinned-out to two Click Module sockets for

which over 300 different MikroElekronika Click peripheral modules are available for purchase from Avnet.

Features:

Access to key peripheral interfaces of LTE System Module via 60 pin Samtec ERM8 series connector (10mm mated connector height. 10mm standoffs required for mounting of LTE Board)

Level-shifting of the WNC module signals to/from 1.8V / 3.3V levels

Dual sockets for two MikroE Click peripheral modules (available from Avnet)

Flexible system prototyping via a choice of over 425 Click peripheral modules

External control of LTE System board power-down and sleep modes

Additional level-shifted GPIO (or PCM Digital Audio) signals (four pins)

Onboard 3.3V and 1.8V voltage regulators
