STM32F103C8T6 ARM STM32 Development Board

This is a core chip based on the STM32F103C8T6 ARM core board, with the following functions:

1. The main board is based on the most basic MCU circuit, 8M and 32768 crystal oscillator circuit, and USB power supply circuit.

2. The core board is divided into two rows, leading to all I/O ports.

3. With SWD simulation debugging download interface, it is simple and convenient, and the debugging speed is fast.

4. Use Micro USB interface, can do USB communication and power supply, USB interface, compatible with ordinary Android mobile phone charger interface.

6. RTC crystal Epson brand, easy to start and more stable.

7. With double pins, but the pins are not welded by default, users can choose the welding direction that suits them according to their own application scenarios.
