Multi vu eurorack: common questions

What microcontroller does the Multi vu eurorack use?

The Multi vu eurorack is built around the ATtiny85, from the AVR/Arduino family.

How big is the Multi vu eurorack PCB?

The Multi vu eurorack measures 41.3 × 109.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Multi vu eurorack?

130 components, from 30 distinct parts. The full bill of materials is listed on this page.

Where can I download the Multi vu eurorack design files?

From the jjradler/multi-vu-eurorack repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Multi vu eurorack design in my own project?

Yes, under the terms of its CC0-1.0 license, which jjradler chose for the repository.

Can I test firmware for the Multi vu eurorack without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
