USBtinyISP microcontroller

via Adafruit

We can get 16 units in Australia from Adafruit. If you order today, we can dispatch this stock between Jul 29, 2021 - Aug 01, 2021.

This is just the microcontroller burned with the USBtinyISP firmware code. If you're buying a kit, this is included. This is intended for people who are buying just the PCB or are experimenting with the kit and want a backup chip.
