1 Overview M660 demo board provides a series of peripheral interfaces, including main power supply

interface, UART interfaces for commissioning and software download, and SIM card interface.

You can perform commissioning after connecting to power supply and serial ports. This document

describes only module commissioning. For details about software update, please refer to module

update document.

2 Interfaces This demo board can be used once connected through power and serial cables.

3.4 M5X0-PWR Board

The above figure shows an M5X0-PWR board, which supplies 3.8V/0.6A power for the module

and outputs 3.3 V CMOS level TXD and RXD for the communication between the computer and

the module and software update. It is connected to the M660 demo board through 4-pin cables,

which have been soldered to the power board in a sequence of red, black, yellow, and green at one

end and should be inserted into the plug of the demo board at the other end. There are two pins on

the power board and they can control the power supply of the module.

Among the 4-pin cables:

Green: TXD, output, 2.85 V CMOS level

Yellow: RXD, input, CMOS level, 3.1 V maximum

Black: Ground

Red: VBAT, 3.6 V to 4.3 V, 3.9 V is recommended

Refer to the silk

print label.



If you want to use this power board to commission the module through serial port on a computer,

install a driver for USB to serial (PL2303 Windows Driver). If you want to use an MCU to control

the demo board, you also need to use the 4-pin cables.

3.5 Commissioning Perform product commissioning directly on a computer through the USB interface. The power

board and demo board are connected as shown in the following figure.

Before the commissioning, you must install the PL2303 Windows Driver. Then, connect the demo

board to a computer as shown in the following figure.

If Prolific USB-to-Serial Comm Port (COM) is displayed under Ports (COM&LPT1) in the

Device Manager pane of the Computer Management window, the serial port is read properly.

Serial Port



Step 1 Start the commissioning tool SecureCRT.

Step 2 Select Serial from the Protocol dropdown list. The following dialog box is displayed.

Select the serial port.

Set Baud rate to

115200 if no specific

requirements.

Select Serial from the

Protocol dropdown list.



Step 3 After setting parameters, click Connect. The port commissioning window is displayed.

4 Material List M660 demo board (including module/excluding module)

M5x0-PWR board

Power and serial cables

Audio interface (optional)

GSM antenna (optional)

If the demo board excludes module, you need to solder it manually.

Terminal display area

You can also input commands and press Enter

to send the commands.

Disconnect the connection to the serial port.
