This was a quick and simple project mainly intended to test creation of a dual-sided board on a PCB mill I recently acquired access to. It will also make it easier and quicker to flash programs onto an ATtiny85, especially when flashing many of them at a time.
I followed this guide to determine which pins should be connected to what in order to flash a program onto an ATtiny85. Photos of the completed board can be seen below:
The board was tested, and it works quite well. It certainly cleans up a bunch of wires!
The board design in Frizting:
As usual, the schematic can be found on my github.
