About the MacroPad PCB

MacroPad is an open source RP2040/RP2350 PCB design by landodoughty, published on GitHub under the MIT license. It is a 2-layer board measuring 79.2 × 106.7 mm, with 109 components from 18 distinct parts.

Its main chip is the C2040, from the RP2040/RP2350 family. Other key parts include the C6186, C97521 and C7484. By type, the board carries 40 diodes, 37 capacitors, 20 switches, 5 resistors, 4 ICs and 2 connectors.

It belongs with the keyboards and displays & leds designs in this gallery.

From the project

A Custom Macro Pad I Designed and Built based on the RP2040

The PCB: In this repository you can find the raw PCB files and the Gerber files which can allow you to manufacture the PCB through a service such as PCBWay or JLCPCB. I have also attached a BOM containing all the parts for the PCB. Most of the parts utilized on the PCB are very standard, and if you are assembling through JLCPCB the BOM already contains LCSC part numbers for most items. The only items which don't have part numbers, because I did not have them assembled through JLCPCB are the USB Micro-B connector, the reverse mount neopixel LEDs, the MX keyswitch sockets, and a small two pin…

MacroPad: common questions

What microcontroller does the MacroPad use?

The MacroPad is built around the C2040, from the RP2040/RP2350 family.

How big is the MacroPad PCB?

The MacroPad measures 79.2 × 106.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MacroPad?

109 components, from 18 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 landodoughty/MacroPad 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 MIT license, which landodoughty chose for the repository.

Can I test firmware for the MacroPad 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.
