Frequently asked questions
Does it work with the Arduino IDE?
Not directly. The Arduino IDE targets AVR and other Arduino cores. This STM8 board needs an STM8 toolchain such as SDCC or ST's tools and is programmed through SWIM with an ST-LINK or compatible programmer.
What supply voltage can I use?
The listed operating range is 3.0V to 5.5V, so a 3.3V or 5V supply falls within the range.
