Eurorack-Modules

This is the central repo for all the "This is not Rocket Science" eurorack modular synth modules.

Please refer to the "Production" folder if you are looking for boards to build. You will find all the design & firmware files for our latest production versions. Artwork is NOT included. Be creative.

All our current development & experiments can be found in the "Development" folder

Sourcecode to the firmware can be found in the Eurorack-KDS repository

Tools needed:

Eagle 7+
Kinetis Development Studio (or whatever the latest NXP/freescale IDE is)
A JTAG probe to flash the initial firmware

Questions

How big is the WhiteRabbit PCB?

It measures 40 × 100 mm and has 2 copper layers, 1.6 mm thick.

What parts does the WhiteRabbit use?

146 parts, built around the RP2040, TPMCP6022T-I/SN, TL072 and ALC5616-CGT. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the WhiteRabbit KiCad files?

From the ThisIsNotRocketScience/Eurorack-Modules repository on GitHub, at the commit this page was made from: the board is Development/Eurorack Set 2021/WhiteRabbit/WhiteRabbit.kicad_pcb and its schematic Development/Eurorack Set 2021/Ducktape_kicad/DAC_&_Trigger_outs.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the WhiteRabbit design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
