MPU-test
About the MPU-test PCB
MPU-test is an open source NXP PCB design by svgeesus, published on GitHub under the MIT license. It is a 2-layer board measuring 39.9 × 75.4 mm, with 13 components from 13 distinct parts.
Its main chip is the Teensy4.1-NE, from the NXP family. By type, the board carries 11 connectors, 1 IC and 1 capacitor.
It belongs with the audio designs in this gallery.
From the project
Eurorack MPE implementation, 2 to 8 voices
Inspired by the use of duophony on the ARP 2600 and Odyssey, this is a MIDI to CV Eurorack module with twin outputs: low-note priority and high-note priority.
Re-utilising designs from the polyphonic Euro-MPE project, this aims to be a high-precison, flexible, and performance oriented duophonic MIDI to Eurorack CV module. It's MPE compatible, so there is independent expression on each of the two notes.

MPU-test: common questions
What microcontroller does the MPU-test use?
The MPU-test is built around the Teensy4.1-NE, from the NXP family.
How big is the MPU-test PCB?
The MPU-test measures 39.9 × 75.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the MPU-test?
13 components, from 13 distinct parts. The full bill of materials is listed on this page.
Where can I download the MPU-test design files?
From the svgeesus/EuroMPE repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the MPU-test design in my own project?
Yes, under the terms of its MIT license, which svgeesus chose for the repository.
Can I test firmware for the MPU-test without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
