STM32G0B1RET6 Development Board

Project Introduction

• This project independently develops a multi-bus interface development board integrated with mainstream serial communication peripherals including I²C, SPI, CAN and LIN.
• All hardware and documents of this project are for study and communication only; commercial use, mass production and unauthorized sales are prohibited.

Core Board & Base Board

Pin Breakout

• I designed the core board as a pluggable structure to facilitate convenient MCU replacement.All spare MCU pins are led out to connectors.

Downloader Interface

• MCU firmware download is supported via the SWD interface. The reserved connector is custom-designed to accommodate both SWD and UART functions. Refer to https://oshwhub.com/grenaf/stlinkv2_1 for details of my self-developed STLINKV2.1.

Power Switch

• As shown, a toggle switch is adopted to switch the power supply. The MCU can be powered either by a 5.0 V DC jack or a Type‑C 5.0 V port.

Peripheral Expansion Board

• This board is designed for learning IIC and SPI communication protocols. The display is driven by ST7789 controller, while the touch IC is FT6336. For detailed information about the display module, please refer to: https://www.lcdwiki.com/zh/3.5inch_IPS_SPI_Module_ST7796.
