How Board Pins Map to STM32 Pins Used in Firmware
This mapping applies to Mesh End Nodes that use the LSN50V3 base board.
1. Board labels and firmware pin names
The pin names printed on the LSN50V3 base board are not always the same as the STM32 pin names used in the firmware.
When reading the board silkscreen or the product pin-definition drawings, use the board pin name. When reading or modifying the firmware, use the STM32 pin name.
