Macropad: common questions

What microcontroller does the Macropad use?

The Macropad is built around the Pico, from the RP2040/RP2350 family.

How big is the Macropad PCB?

The Macropad measures 112.5 × 81 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Macropad?

33 components, from 3 distinct parts. The full bill of materials is listed on this page.

Where can I download the Macropad design files?

From the siddarthreddygsr/macropad repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Macropad design in my own project?

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

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.
