1. External crystal socket
insert crystal to the holes on two sides regardless of the middle hole
2. MCU selection jumpers A
- 8L for STM8L series
- 8S/8A for STM8S/STM8A series
3. SWIM port
- For programming/debugging/testing
- Compatible with ST-LINK ST-LINK/V2 etc.
4. Pin headers connected to MCU pins
- Clearly labeled with onboard marks
- Sasy for testing and further expansion
5. Power indicator
6. MCU selection jumpers B
- STM8L series: needs no configuration just open OR ignore them
- STM8S series: short the upper two pins for STM8S207/STM8S105 short the lower two pins for STM8S103/STM8S903
- STM8A series: short the upper two pins
7. Power input: DC5V/3.3V
