This is a header board I've designed for STM8S207R8T6.
5v and GND pins on both rows of pinouts
Full access to GPIO even PA1 and PA2 which can be used for OSC
CH340 USART to USB with mini USB
Pins specified for SWIM
The Altium files and the BOM is attached in the link:
A note on designing based on STM8 MCUs:
There is a pin on the STM8 called VCAP which according to documentation is the 1.8v output of the internal regulator used to power the core of the MCU. If you leave this pin on it's own, it will reset the MCU every 100ms. In order to avoid this disaster the VCAP pin has to be decoupled with a 470 nf capacitor at minimum. The ideal capacitor for this is 680 nf.
I'd love to hear feedback.
