Development Board designed for the STM8S207Cx series microcontrollers


A development board for the STM8S207Cx series microcontrollers, such as STM8S207C6, STM8S207C8, STM8S207CB. It is designed to give designers a quick start to develop code on these devices.

This development board comes with the STM8S207CxT6 chip.

What's On Board

  • Power
    • Powered from external 5V power supply through DC jack
    • Power input/output pin headers
      • spare power input port
      • convenient for providing power supply to other board/device if necessary
    • Jumper for configuring voltage level to be applied, 5V/3.3V
  • Onboard Chips
    • STM8S207CxT6 (LQFP48), the STM8 Microcontroller
    • AMS1117-3.3, on board regulator
  • Interfaces
    • SWIM port for programming/debuging, compatible with ST-LINK
    • BUS-A & BUS-B, for connecting to the expansion board DVK501, ease to study/develop various peripheral devices
  • Human to Machine Interface
    • Reset button, used to reset the system
    • Power indicator LED
    • 3 Capacitive touchkeys, make it easy to work with the STM8 Touch Sensing Library
  • Other Features
    • External crystal configurable
      • there is a jumper for selecting on board 8M crystal or custom crystal mounted via the socket
    • All the MCU pins are accessible on expansion connectors for further expansion
    • All the pins are clearly marked on the PCB. These marks provide the basic information on the pins
