Product Introduction

  • This is a core chip based on for CS32F103C6T6 ARM core board; features are as follows:
  • The board is based on the most basic MCU circuit, 8M and 32768 crystal circuit, and USB power supply circuit.
  • The core board is divided into two rows leading to all the I / O ports.
  • With the SWD simulation debug download interface, simple and convenient debugging speed.
  • With the Mirco USB interface, you can do USB communication and power supply; the USB interface is compatible with the standard Andrews mobile phone charger interface.
  • RTC crystal Epson brand is easy to start and more stable.
  • With a double pin, but the pin does not default welding, the user chooses their welding direction according to their application scenarios. If welding is required, please tell the owner.
  • Keil can be used to compile, IAR compiler can be downloaded through the J-Link or USART 1 procedures; the procedures are the owner and debugging procedures; problems can consult the owner.
