Product Introduction
This is a core chip based on STM32F103C8T6 ARM core board, features as follows:
1- The board based on the most basic MCU circuit, 8Mhz 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 mobile phone charger interface.
5- RTC crystal Epson brand, easy to start, more stable.
6- Keil can be used to compile, IAR compiler, can be downloaded through the JLink or USART1 procedures, the procedures are the owner and debugging procedures.
