Macro microcontroller-2: common questions

What microcontroller does the Macro microcontroller-2 use?

The Macro microcontroller-2 is built around the RP2040, from the RP2040/RP2350 family.

How big is the Macro microcontroller-2 PCB?

The Macro microcontroller-2 measures 96.5 × 35.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Macro microcontroller-2?

43 components, from 25 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 microcontroller-2 design files?

From the Nicholas1023/macro-microcontroller-2 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 microcontroller-2 design in my own project?

Yes, under the terms of its CERN-OHL-W-2.0 license, which Nicholas1023 chose for the repository.

Can I test firmware for the Macro microcontroller-2 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.
