WhiteRabbit: common questions
What microcontroller does the WhiteRabbit use?
The WhiteRabbit is built around the MMBT3906, from the RP2040/RP2350 family.
How big is the WhiteRabbit PCB?
The WhiteRabbit measures 40 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the WhiteRabbit?
146 components, from 79 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the WhiteRabbit design files?
From the ThisIsNotRocketScience/Eurorack-Modules repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the WhiteRabbit design in my own project?
Yes, under the terms of its MIT license, which ThisIsNotRocketScience chose for the repository.
Can I test firmware for the WhiteRabbit without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
