About the Hackpad PCB
Hackpad is an open source PCB design by Sacul518, published on GitHub under the MIT license. It is a 2-layer board measuring 68 × 99.7 mm, with 21 components from 5 distinct parts.
Other key parts include the MOUDLE-SEEEDUINO-XIAO. By type, the board carries 10 switches, 9 diodes, 1 IC and 1 connector.
It belongs with the keyboards and displays & leds designs in this gallery.
From the project
9-key mechanical macropad with rotary encoder + OLED, built on a Seeed XIAO RP2040. Hack Club Hackpad YSWS.
A custom 9-key mechanical macropad with a rotary encoder and OLED display, built around the Seeed XIAO RP2040. Designed from scratch in KiCad as part of Hack Club's Hackpad YSWS.
I wanted a macropad that isn't just static keys but actually adapts to what I'm doing — so the rotary encoder browses through profiles (turn to preview on the OLED, click to confirm) and every one of the 9 keys is freely configurable through a desktop app, either as a key combo or a custom script.
