UPDATED GUIDE: Adafruit UPDI Friend #AdafruitLearningSystem #Adafruit @adafruit

UPDI stands for Unified Program and Debug Interface, but this board is so smol and cute that we will call it the Unusually Playful Device Interfacer and pat its head when it does a good job. It’s designed to make programming modern ATtiny chips very easy because it has 3V or 5V power and logic select, power and transmit indicator LEDs, and a quick cable for poking into a breadboard.

The Adafruit UPDI Friend guide has been updated to include resources for the High Voltage UPDI Friend. There are new pages for Pinouts and instructions on how to enable settings in the megaTinyCore board support package to enable the high-voltage fuses settings. Beware though- you should only use this High Voltage UPDI Friend for chips that have a high voltage programmer. Otherwise, you will brick your board.
