From the project

An open-source, minimal footprint STM32F103C8T6 development board designed in KiCad, featuring dedicated I2C and USB interfaces.

This repository documents the complete design and fabrication files for a compact, USB-powered development and evaluation board built around the STM32F103C8T6 microcontroller (ARM Cortex-M3 core). The board is intended to serve as a minimal, self-contained platform for rapid hardware prototyping and peripheral evaluation.

The design breaks out essential MCU peripherals to accessible headers, with particular emphasis on a dedicated I2C expansion interface to facilitate straightforward integration with standard sensors, displays, EEPROMs, and other I2C-compatible devices. The overarching…
