STM32F103C6T6 STM32 32KFlash 10KRam minimum system board core board

Different from STM32F103C6T6 STM32F103C8T6

This is the main chip based on the ARM motherboard. CS32F103C6T6 has the following features:

1, The board uses the most basic MCU circuit, 8M 32768 crystal circuit and USB power supply circuit.

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

3With SWD emulation debug download interface, easy to use and convenient, debugging speed.

4. The use of micro USB interface, you can communicate via USB and power supply, USB interface is compatible with ordinary Andrews mobile phone charger interface.

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

7, with double pin, but the pin does not start welding, users according to their own use situation to choose their own welding direction. If welding is required, please tell the owner.

Keil can be used to compile the IAR compiler can be downloaded through the J-Link procedure or the USART1 procedure. The procedure is the owner and the debugging process, so there is a problem can consult the owner.
