About the HackPad PCB

HackPad is an open source PCB design by doopyelephant, published on GitHub. It is a 2-layer board measuring 120.5 × 76.5 mm, with 34 components from 4 distinct parts.

Other key parts include the MOUDLE-SEEEDUINO-XIAO. By type, the board carries 16 switches, 16 diodes, 1 IC and 1 connector.

It belongs with the keyboards designs in this gallery.

From the project

A 16 Key HackPad with a salvaged Touchpad used for swipe gestures and other things.

Aswell as a place to solder on the 12 pin FFC(Flat Flexible Connecter) that connects to the touchpad. The pinout of the touchpad was reverse engineered with a multimeter and a few partial labels on the donor board, I believe the touchpad uses the PS/2 protocol(the circular mouse port from the 90s) with a few modifications:

- FFC instead of circular port - The Two extra pins in the spec are used to relay LB and RB through the touchpad like: LB & RB -> Touchpad -> SOC ## Firmware This Hackpad uses QMK (QMK suprisingly has support for PS/2! )
