Optimized for industrial automation prototypes, smart home controllers, and robotics applications that require GPIO expansion and realtime data processing in spaceconstrained environments. The STM32F103C8T6 Development Board combines a performance ARM CortexM3 core running at 72 MHz with 40 programmable I/O pins, USART/I2C protocols, and USBtoserial conversion to support efficient development for IoTs, robotics, and smart device projects. Built with industrial materials, this minimumsystem STM32F103C8T6 board offers improved signal stability and durability compared with generic modules, while remaining IDEcompatible through drivers. Tworow pin layout exposes all 10 ports with SWD download interfaces; features a TypeC port for power and USB flexibility, a usercontrolled PC13 LED, and reset/BOOT mode buttons to streamline debugging. Use scenarios Industrial automation prototyping: Expand GPIO to interface with sensors, actuators, and local controllers in compact, robust hardware suitable for proofofconcept and pilot deployments. Robotics development: Use the MCU for motor control, sensor fusion, and realtime processing in small robotic platforms, with convenient USBserial connectivity and straightforward debugging. IoT and smart devices: Build edgeprocessing devices that require reliable IO, realtime data handling, and easy integration with IDE tooling and drivers for rapid firmware iteration.
