Unicorn

This circuit board is visually based on the Rainbow Unicorn. However, the component placement is the same as the Bau(m)satz.

Thus, the functionality is mostly based on the Digistump. It also contains the microcontroller ATtiny85 and the USB circuit.

It can therefore be programmed in the same way.

In addition to the Digistump, 6 LEDs are connected to PB0, PB1 and PB2 via Charlieplexing.
