About the EinsteinTC01PS2 PCB

EinsteinTC01PS2 is an open source PCB design by Board-Folk, published on GitHub. It is a 2-layer board measuring 77.9 × 86.5 mm, with 21 components from 14 distinct parts.

Other key parts include the MT8816. By type, the board carries 8 resistors, 4 diodes, 3 transistors, 3 connectors, 1 IC and 1 capacitor.

From the project

Tatung Einstein TC-01

The Arduino Nano version of a PS/2 keyboard adapter for the Einstein TC-01. This is a larger version of the board intended for development of the Arduino code for it, though is perfectly usable. The board uses separate pins from the Nano to pull Shift, Ctrl and Grph through BC517 darlington pairs.

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.
