7.2 Cellular STMod+ expansion board
The expansion board is a GSM/UMTS/HSDPA modem based on Quectel UG96 module. The UG96 is a GSM 4-Band 800/850/900/1900/2100, UMST 5-Band 800/850/900/1900/2100 supporting HSDPA. The connection with the STM32L496AGI6-based Discovery mother board is done through the STMod+ connector.

7.2.1 Modem power supply and reset
The cellular board is supplied through the 5V on the STMod+ connector (Pins 6 and 15). The modem is enabled by the power enable (Pin 9). When this pin is driven, a few seconds later, the red led is on to indicate that the modem is ready, and the green led starts flashing to indicate that the modem is scanning for cell synchronization. At this time AT command can be sent using UART.
If the power supply is not enough in signaling mode, additional power supply can be provided by the USB connector.
7.2.2 SIM selection
Switchable SIM interface is provided on the cellular modem board. The user selects either the embedded SIM or the plastic SIM.
Set pin Sim_select0 to low to select the plastic SIM, or to high to select the embedded SIM.
7.2.3 Modem firmware update.
The modem firmware can be updated using the micro USB connector provided on the modem:
1. First install the USB drivers of the modem from Quectel.
2. Install Qflash from Quectel and load the firmware.
3. Press start and reset the modem to download the firmware.

7.3 Embedded ST_LINK/V2-1
The ST-LINK/V2-1 programming and debugging tool is integrated on the STM32L496AGI6-based Discovery mother board. Compared to ST-LINK/V2 the changes are listed in Section 7.3.1.
7.3.1 Drivers
The ST-LINK/V2-1 requires a dedicated USB driver, available on www.st.com for Windows 7 and 8. On Windows XP the ST-LINK/V2-1 driver requires WinUSB to be installed before using the ST-LINK/V2-1 (either available from Microsoft website or included in the USB driver for ST-LINK/V2 for XP).
When the STM32L496AGI6-based Discovery mother board is connected to the PC before the driver is installed, some STM32L496AGI6-based Discovery mother board interfaces may be declared as ‘Unknown’ in the PC device manager. In this case the user must install the driver files, and update the driver of the connected device from the device manager.
Note: Prefer using the ‘USB Composite Device’ handle for a full recovery.
Figure 4. USB Composite Device driver installation.
7.4 Mother board power supply
7.4.1 Power supply sources
The STM32L496AGI6-based Discovery mother board is designed to be powered by the following sources:
• STLK from the ST-LINK/V2-1 USB connector CN5 with 500 mA current limitation
• Power mechanism of supplying the board by STLINK/V2-1
• Programing/debugging when the power supply is not from ST-LINK/V2-1
It is mandatory to power the board first using user USB FS connector CN8 or the VIN pin of Arduino connector CN15 before connecting the USB cable from ST-LINK/V2-1 CN5 to the PC. Proceeding this way ensures that the enumeration succeeds thanks to the external power source.
Hardware layout and configuration UM2322
12/22 UM2322 Rev 2
The following power sequence procedure must be respected:
1. Put a jumper in JP3 at location U5V to use power from user USB CN8 or at location E5V to use power from VIN of Arduino connector CN15.
2. Connect the corresponding external power source.
3. Check the green LED LD8 is turned ON.
4. Connect the PC to ST-LINK/V2-1 USB connector CN5.
If this order is not respected, the board may be powered by VBUS first from ST-LINK, and the following risks may be encountered:
1. If more than 500 mA current is needed by the board, the PC may be damaged or current may be limited by PC. As a consequence the board is not powered correctly.
2. 500 mA is requested at the enumeration, so there is a risk that the request is rejected and enumeration does not succeed if PC does not provide such current.
7.5 Mother board reset sources
The reset signal of the STM32L496AGI6-based Discovery mother board is low active and the reset sources include:
• Reset button B1
• Embedded ST-LINK/V2-1, SW1 set to ON (default setting)
• Arduino compatible TM connector CN15 pin 3
7.6 Mother board boot options
After reset, the microcontroller STM32L496AGI6 may boot from the 3 following embedded memory locations depending on bits BOOT0 and BOOT1:
• Boot from the user FLASH memory
• Boot from the ICP (In Circuit Programming)
• Boot from the SRAM
The selection of the memory space for the boot is done by two bits, BOOT0 and BOOT1. The value of BOOT1 is defined by a user option bit (bit[23], nBOOT1). Specifically, when this bit is written with '1', the empty flag status toggles and keeps this new status until the next OBL or until a new '1' is written.
