Mpe32sensor
About the Mpe32sensor PCB
Mpe32sensor is an open source PCB design by udu3324, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 16 × 21 mm, with 6 components from 5 distinct parts.
Other key parts include the TMAG5273A1. By type, the board carries 3 connectors, 1 IC, 1 diode and 1 capacitor.
It belongs with the audio designs in this gallery.
From the project
an expressive midi controller that has onboard sound processing with super hackable io
Built in DSP Support for Programs and Sequencer Hacker Header Exposed GPIO Micro-SD Card Support * Onboard SDRAM for extended recording/memory
There is sample code here for trying out the mpe32sensors standalone on the Arduino platform.
Each key is press fit and can also be screwed in with a m3 screw and nut if needed.
Due to my 3d-printer being too small, I have to cut the board in half to print. This is later adhered with uv-glue.
