Overview
![connecting the two boards](/img/devkit/EX-STM8-Q64a-207/connection-with-DVK501.jpg)
A complete starter kit and development system for the STM8S207Rx series microcontrollers, such as STM8S207R6, STM8S207R8, STM8S207RB. It is designed to give designers a quick start to develop code on these devices.
This development system contains a main development board with the STM8S207RxT6C chip, and an additional expansion board with various peripheral devices.
The BUS-A & BUS-B headers located on both boards should be used to connect the two boards via 10-pin cables, which are delivered with the product. As shown in the figure right.
