About the Macropad v2 PCB

Macropad v2 is an open source RP2040/RP2350 PCB design by daaminashai, published on GitHub under the MIT license. It is a 2-layer board measuring 80 × 100 mm, with 34 components from 3 distinct parts.

Its main chip is the XIAO-RP2040-DIP, from the RP2040/RP2350 family. By type, the board carries 17 diodes, 16 switches and 1 IC.

It belongs with the keyboards designs in this gallery.

From the project

another custom macropad - made from scratch.

I made a similar looking keyboard and wanted something to pair with it. This is a similar looking device and will probably use the extra keycaps I got with that keyboard.

There were none for the most part, this was my 4th time making a macropad/keyboard. I tried to speedrun it. It took me less 2 hours to make the PCB and Case.

This contains 16x Switches and 1x Rotary Encoder. I'll probably assign music related macros to the RE and switches. The MCU is a Seed Xiao RP2040 which has usb-c. The case has a bottom and a two-in-one top, with the middle plate being inbuilt. I use heatset inserts to…

Macropad v2: common questions

What microcontroller does the Macropad v2 use?

The Macropad v2 is built around the XIAO-RP2040-DIP, from the RP2040/RP2350 family.

How big is the Macropad v2 PCB?

The Macropad v2 measures 80 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Macropad v2?

34 components, from 3 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 v2 design files?

From the daaminashai/macropad-v2 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 v2 design in my own project?

Yes, under the terms of its MIT license, which daaminashai chose for the repository.

Can I test firmware for the Macropad v2 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.
