This is a core chip based on STM32F103C8T6 ARM core board, features are:
The board based on the most basic MCU circuit, 8M and 32768 crystal circuit, USB power circuit.
The core board is divided into two rows leading to all I / O ports.
With SWD simulation debug download interface, simple and convenient, debugging speed.
Using the Mirco USB interface, you can USB communication and power supply, USB interface, compatible with the ordinary Andrews mobile phone charger interface.
RTC crystal Epson brand, easy to start, more stable.
With double pin, but the pin does not default welding, the user according to their own application scenario choose their own welding direction. If welding is required, tell the owner.
