/** @file board.c
 * @brief Board file x STM32W108 Kits boards 
 *
 * This file implements a software layer to support all the ST kits boards
 * and deal with the difference in leds, buttons and sensors connected to the board.
 * This a bit too complex for customer boards adaptation and customer can simplify it
 * to adapt it to their hardware environment as they normally don't need to have the software
 * running on several boards.
 * The boards supported are:
 * - MB851 A
 * - MB851 B
 * - MB851 C
 * - MB954 A
 * - MB954 B
 * - MB950 A
 * - MB951 A
