Other key parts include the 0. By type, the board carries 9 LEDs, 9 diodes, 1 IC and 1 switch.

It belongs with the keyboards designs in this gallery.

From the project

cheap macro pad with rot encoders and joystick support

The Farewell is the cheapest 3x3 macropad I could make, with joystick and rotary encoder support.

The cost per unit is around $13 with switches, encoders, diodes and keycaps, for 10 units.

Disclaimer : This is not a final design. Problems identified following the first batch are listed in the "To do" section.
