STM32F103C8T6 expansion board

Overview

This STM32F103C8T6 minimum system expansion board is designed for learning STM32F103C8T6 microcontrollers. It features a wide input voltage range of 6~35V and a maximum output of 5V5A, sufficient for most applications.
The board uses the XL4005 step-down chip, ensuring stable output voltage and low ripple. It supports 4~5 large servos, with inputs via XT60 or terminal blocks, and includes an 8-pin LCD interface. **
Important Note:** The feedback resistor in the step-down circuit should ideally have 1% accuracy; otherwise, the output voltage deviation will be significant.
Future development may consider adding a motor drive module, a 2.4GHz module, a Bluetooth module, and an MPU6050.
