Mt32-pi zero breakout: common questions

What microcontroller does the Mt32-pi zero breakout use?

The Mt32-pi zero breakout is built around the 2222, from the Raspberry Pi family.

How big is the Mt32-pi zero breakout?

The Mt32-pi zero breakout measures 65 × 30 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mt32-pi zero breakout?

13 components, from 13 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 Mt32-pi zero breakout design files?

From the wiretap-retro/mt32-pi-zero-breakout repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Mt32-pi zero breakout design in my own project?

Yes, under the terms of its Unlicense license, which wiretap-retro chose for the repository.

Can I test firmware for the Mt32-pi zero breakout without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
