The digispark is the unofficial brother of the Arduino, who was helped out into the world via kickstarter. This small board contains only a voltage regulator and an Attiny85 as a microcontroller. This module can be plugged directly into a computer and programmed with the Arduino IDE, no separate programmer is required. https://elecena.pl/product/27738768/opencircuit-digispark 2025-01-22 https://elecena.pl/product/27738768/opencircuit-digispark 2025-03-22 https://elecena.pl/product/27738768/opencircuit-digispark 2026-02-23 https://elecena.pl/product/27738768/opencircuit-digispark 2026-02-25 https://elecena.pl/product/27738768/opencircuit-digispark 2026-04-11
