Elecbee STM32F103C8T6 System Board Imported SCM Core Board STM32 ARM Development Board

Description:

This is a core chip based on the STM32F103C8T6ARM 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 Mirco 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.
