Product details
The STM8S103F3P6 circuit uses the STM8S103F3P6 chip from STMicroelectronics. The STM8S103 is an 8-bit microcontroller that supports 8 Kbytes of Flash memory plus integrated EEPROM memory. They provide benefits such as: High performance, stable speed, high durability, reduced system cost. Programs can be written and deleted up to 100,000 times thanks to the built-in EEPROM memory. Operating frequency 16MHz, independent watchdog with separate clock source.

The module is powered by microUSB 5V, SWIM or power pin, the board includes AMS1117-3.3V LDO to convert USB 5V to 3V3 VDD.

On the Arduino Board there is also 1 power LED, 1 LED connected to pin B5 and a reset button.
