STM32G431CxU6 development board

Overview

# Development Board Introduction
* The smallest system development board based on STM32G431CBU6, UQFPN package, 128Kb Flash, 32Kb Sram, main frequency up to 170MHz, supports hardware CORDIC, FMAC.
* Lead out all IO except USB FS, onboard Typec interface for power supply, firmware download through USB DFU. Lead out SWD interface.
* Onboard 8MHz external high-speed crystal oscillator and low-speed crystal oscillator.
* Onboard power indicator and one user indicator.
* Onboard NRST and BOOT0 buttons for easy selection of boot mode.
* Lead out the reference voltage port, select by welding resistor.
* You can choose to use the internal clock instead of welding the external clock.
* The proof has been verified, the function is normal, and the USB device is normal.
* Provide a USB Keyboard Device firmware.
