This is a core chip based on for CS32F103C8T6 ARM core board, features are as follows: 1. the board based on the most basic MCU circuit, 8M and 32768 crystal circuit, USB power supply circuit. 2. the core board is divided into two rows leads to all the I / O port. 3. with SWD simulation debug download interface, simple and convenient, debugging speed. 4. the use of the Mirco USB interface, you can do USB communication and power supply, USB interface, compatible with the ordinary Andrews mobile phone charger interface. 6. RTC crystal Epson brand, easy to start, more stable. 7. with double pin, but the pin does not default welding, the user according to their own application scenarios to choose their own welding direction. If welding is required, please tell the owner. Keil can be used to compile, IAR compiler, can be downloaded through the J-Link or USART1 procedures, the procedures are the owner and debugging procedures, there are problems can consult the owner.
