The B-G431B-ESC Discovery kit board is based on the STM32G431CB microcontroller,
|
|
the L6387 driver and STL180N6F7 power MOSFETs.

UART/USART PINS
|
|
---------------
|
|
|
|
USART2 is accessible through J3 pads and ST LINK Virtual Console:
|
|
USART2_TX - PB3
|
|
USART2_RX - PB4
|
|

|
|
Configures the NuttShell (nsh) located at apps/examples/nsh. The
|
|
Configuration enables the serial interfaces on USART2.
