Penrose is a simple CV quantizer DIY kit for the eurorack format. It takes an incoming continuous CV voltage and converts it to the nearest note in a scale. Active notes can be selected with the 12 buttons. You can use it to tune the output of your analog sequencer, as a semi random melody generator, for fast chiptune arpeggios and much more.

This is an option to buy the Panel/PCB + Programmed Firmware Chip, support is not provided to help you source the other parts, read the documentation first before deciding if this project is for you.

The project is open source, so the schematic and source code is available.
