About the MacroPad Controller Board

MacroPad Controller Board is an open source RP2040/RP2350 PCB design by loredavid, published on GitHub under the CERN-OHL-S-2.0 license. It is a 2-layer board measuring 70 × 50.5 mm, with 29 components from 26 distinct parts.

Its main chip is the 1, from the RP2040/RP2350 family. By type, the board carries 25 test points, 1 IC, 1 connector and 1 capacitor.

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 Controller Board: common questions

What microcontroller does the MacroPad Controller Board use?

The MacroPad Controller Board is built around the 1, from the RP2040/RP2350 family.

How big is the MacroPad Controller Board?

The MacroPad Controller Board measures 70 × 50.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MacroPad Controller Board?

29 components, from 26 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 Controller Board 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 Controller Board design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which loredavid chose for the repository.

Can I test firmware for the MacroPad Controller Board without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
