MacroPad
About the MacroPad PCB
MacroPad is an open source PCB design by loredavid, published on GitHub under the CERN-OHL-S-2.0 license. It is a 2-layer board measuring 144 × 79 mm, with 59 components from 15 distinct parts.
By type, the board carries 20 diodes, 20 capacitors, 11 test points and 8 switches.
It belongs with the keyboards and displays & leds designs in this gallery.
From the project
A 6 button macropad with a display for button labels and a mouse knob with haptic feedback! — v2 redesign: new Pico SDK firmware + USB configurator.
A six-key macropad with an OLED label screen and a brushless wheel that generates its detents in software — the clicks you feel are torque curves, not a mechanical ratchet, so every profile can have a different feel.
Version 2 is a ground-up firmware rewrite on the Raspberry Pi Pico SDK, plus a desktop configurator that sets up the whole device over the USB cable. The hardware is unchanged from the original project by dmcke5 — the same two PCBs and the same printed parts run this firmware without any rewiring.

MacroPad: common questions
How big is the MacroPad PCB?
The MacroPad measures 144 × 79 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the MacroPad?
59 components, from 15 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the MacroPad design files?
From the loredavid/Hapticpad repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the MacroPad design in my own project?
Yes, under the terms of its CERN-OHL-S-2.0 license, which loredavid chose for the repository.
