Custom Macropad: common questions

What microcontroller does the Custom Macropad use?

The Custom Macropad is built around the XIAO-RP2040-SMD, from the RP2040/RP2350 family.

How big is the Custom Macropad PCB?

The Custom Macropad measures 92 × 67 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Custom Macropad?

15 components, from 4 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 Custom Macropad design files?

From the joshujo/joshujo-s-Custom-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 Custom Macropad design in my own project?

The repository has no license, so all rights stay with joshujo. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Custom 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.
