![]() Since the Digispark is simply a small break out board for the ATtiny85 MCU, you can also use this Instructable to rescue fuses on a stand alone ATtiny85 MCU.Ī sketch for Uno is available here for unlocking ATtiny85:Ĭode is by Paul Willoughby and original article for unlocking bare ATtiny85 ICs here: If you continue to use the board as a Digispark, the P5 pin has been converted from a regular I/O pin to a reset pin. Using this method you can continue to use the board as a Digispark, or use it as a plain ATtiny85 breakout board and program it via ISP, or use it as a Trinket. You can also use a Nano or Pro Mini, which are simply small Unos. In this Instructable, I use an Uno as the high voltage programmer, and later I use it as an ISP. I have a clone Digispark, which works the same as the Kickstarter Digispark from Digistump. This Instructable documents how I unlock the reset pin and program the Digispark with ISP programming to convert it to a Trinket. Use a different bootloader, such as Trinket. ![]()
