MidiMood: common questions

What microcontroller does the MidiMood use?

The MidiMood is built around the Arduino_Pro_Micro, from the AVR/Arduino family.

How big is the MidiMood PCB?

The MidiMood measures 422.4 × 118.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MidiMood?

45 components, from 8 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 MidiMood design files?

From the silveirago/MidiMood repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the MidiMood design in my own project?

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

Can I test firmware for the MidiMood without the hardware?

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