Introduction

"XBoard Standard Development Board" is a series of development boards with different main controls but consistent appearance and pin functions. The main uses of this series of development boards are inter-board communication protocol testing (development board + development board), single module testing (development board) board + evaluation board)

Currently contains:

XBoard standard development board-STM32F103RET6 (this project)

XBoard standard development board-STM32G474RET6: https://oshwhub.com/Knight_Sin/standard-dev-board-stm32g474ret6

XBoard standard development board-ESP-WROOM-32U: https://oshwhub.com/Knight_Sin/standard-dev-board-esp-wroom-32u

Compatible evaluation boards:
