## Board with STMOD+ Connector
### DISCO_L496AG
https://os.mbed.com/platforms/ST-Discovery-L496AG/
Default HW configuration:
- STMOD pins 1, 2, 3 and 4 are mapped to UART CTS/TX/RX/RTS
BG96 expansion board is fully compatible.
### DISCO_L4R9I
https://os.mbed.com/platforms/DISCO-L4R9I/
Default HW configuration:
- STMOD pins 1 and 2 are mapped to SPI
- STMOD pins 2 and 3 are mapped to UART TX/RX
BG96 expansion board can be used but without flow control.
### DISCO_H747I
https://os.mbed.com/platforms/ST-Discovery-H747I/
Default HW configuration:
- STMOD pins 1, 2, 3 and 4 are mapped to SPI
BG96 expansion board can not be used without solder bridges update
