Einstein TC01 PS2 Mini v1

‍

The smaller ATMEGA328 version of a PS/2 keyboard adapter for the Einstein TC-01. The board uses separate pins from the Nano to pull Shift, Ctrl and Grph through BC517 darlington pairs. This version doesn't include indicator LEDs for these.

The board needs a separate 5V power connection as there is no power output on the Einstein's keyboard header. Footprints for both a barrel jack and 2 pin XH connector are provided for this.

There are 3 rows of pin headers, the centre row being 2.54mm, the other 2 2.50mm same as the main board. This arrangement could be use for passthrough to an existing keyboard if necessary.

Code

Code can be found in the EinsteinTC01PS2 folder, including the compiled binaries for the ATMEGA328. See any notes in there. The Minipro TL866 II can be use to program that. These settings work:
