7Semi STM32G0B1RET6 Development Board – High Performance ARM Cortex-M0+ Board

The 7Semi STM32G0B1RET6 Development Board is a compact and versatile development platform built around the STM32G0B1RET6, a 32-bit Arm Cortex-M0+ microcontroller operating at up to 64 MHz. With 512 KB Flash memory and 144 KB SRAM, the board provides ample resources for embedded control, industrial automation, sensor interfacing, communication systems, motor control, and IoT applications.

The board brings out the STM32G0B1RET6’s major GPIO and peripheral interfaces through accessible headers, making it suitable for rapid prototyping and custom embedded development. It supports multiple communication interfaces including USART, LPUART, I²C, SPI, and FDCAN, along with ADC, DAC, timers, comparators, and other integrated peripherals. Programming and debugging are performed through the SWD interface using an ST-Link compatible programmer.

A USB Type-C connector is provided for 5 V power input only; the USB data lines are not connected to the MCU. An onboard user-programmable LED connected to PB1 provides a convenient indicator for testing, debugging, and application status.
