About the MidiMonger components PCB

MidiMonger components is an open source STM32 PCB design by dchwebb, published on GitHub. It is a 2-layer board measuring 40 × 100 mm, with 64 components from 28 distinct parts.

Its main chip is the STM32F446RETx, from the STM32 family. Other key parts include the TL074, 74HCT244, MAX5134, 6N137 and LM1117-3.3. By type, the board carries 23 resistors, 21 capacitors, 7 ICs, 7 connectors, 4 diodes and 1 crystal.

It belongs with the audio designs in this gallery.

From the project

Eurorack MIDI interface supporting USB and serial MIDI. Based on ARM STM32F446 MCU.

MidiMonger is a Eurorack MIDI interface supporting USB and serial MIDI.

MIDI Monger is a configurable MIDI interface for controlling Eurorack modules from either USB MIDI or Serial MIDI (or both simultaneously). MidiMonger 2 adds support for USB host functionality allowing the use of USB MIDI controllers (and experimentally USB HID mice) to control Eurorack modules.

MidiMonger components: common questions

What microcontroller does the MidiMonger components use?

The MidiMonger components is built around the STM32F446RETx, from the STM32 family.

How big is the MidiMonger components PCB?

The MidiMonger components measures 40 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MidiMonger components?

64 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the MidiMonger components design files?

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

Can I use the MidiMonger components design in my own project?

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

Can I test firmware for the MidiMonger components without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
