Not A USB Drive.

Digispark T85

Looks like a flash drive, but hides an ATtiny85: six pins, a few kilobytes of flash, and a surprising amount of USB mischief.

Good to know

  • Upload is backwards: click Upload in the IDE FIRST, then plug it in – the first ~5 s belong to the bootloader.
  • P3/P4 are USB D-/D+ (with zeners) – avoid them if you can.
  • No classic serial monitor, USB is bit-banged (V-USB).
  • P5 is reset by default; without burning fuses it is a weak output.
