Macro pad: common questions

What microcontroller does the Macro pad use?

The Macro pad is built around the RP2040, from the RP2040/RP2350 family.

How big is the Macro pad PCB?

The Macro pad measures 72 × 110 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Macro pad?

83 components, from 23 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 Macro pad design files?

From the kgalinec/macro-pad 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 Macro pad design in my own project?

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

Can I test firmware for the Macro pad 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.
