MIDI-: common questions

What microcontroller does the MIDI- use?

The MIDI- is built around the RaspberryPi_Pico, from the RP2040/RP2350 family.

How big is the MIDI- PCB?

The MIDI- measures 193 × 154.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MIDI-?

87 components, from 5 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 MIDI- design files?

From the adirock09/MIDI- 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 MIDI- design in my own project?

The repository has no license, so all rights stay with adirock09. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the MIDI- 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.
