 *
 * ### User Interface
 *
 * 3 Buttons:
 *
 * | NAME   | BOOT     | D0        | RESET |
 * |:------ |:---------|:--------- |:----- |
 * | Pin    | PA0 (IN) | PB13 (IN) | NRST  |
 *
 * 1 LED:
 *
 * | NAME   | D5    |
 * | -----  | ----- |
 * | Color  | red   |
 * | Pin    | PB5   |
 *
 * ### Flash the board
 *
 * The BOARD comes pre-flashed with a Factory AT Firmware with RDP (Read Protection)
 * level 1, this needs to be removed to enable subsequent flashing. The easiest
 * way is with STM32CubeProgramer as described in [seedstudio wiki](https://wiki.seeedstudio.com/LoRa-E5_STM32WLE5JC_Module/#2-develop-with-stm32cube-mcu-package).
 *
 * Once read protection is removed subsequent flashing can be performed with and
 * attached ST-LINK on the SWD pins (do not connect RST but only GND, SWCLK and SWDIO).
 *
 * ```
 * BOARD=lora-e5-dev make flash
 * ```
 *
 * The default used programmer is OpenOCD.
 *
 * ### Serial connection
 *
 * The default serial connection is through the USB-C port mapping to PB7 (RX) and
 * PB6 (TX) UART pins (a second UART and an LPUART interface is also exposed).
