MacSplit60: common questions

What microcontroller does the MacSplit60 use?

The MacSplit60 is built around the Pico, from the RP2040/RP2350 family.

How big is the MacSplit60 PCB?

The MacSplit60 measures 166.1 × 112 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MacSplit60?

68 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the MacSplit60 design files?

From the neerajadsul/Stagy58 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the MacSplit60 design in my own project?

Yes, under the terms of its MIT license, which neerajadsul chose for the repository.

Can I test firmware for the MacSplit60 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.
