Adafruit High Voltage UPDI Friend - USB Serial UPDI Programmer raspberry wire up to 20 km withThe UPDI High Voltage Friend is a compact and efficient programmer designed to make programming modern ATtiny chips easier. It features a 3V or 5V power and logic select, indicator LEDs for power and transmission, and a quick cable for easy breadboard connections. This board is a High Voltage (HV) version, capable of sending a 12V pulse to the UPDI pin before programming, which is essential for chips using UPDI as a reset or GPIO. Additionally, it
