Laser controller: common questions

What microcontroller does the Laser controller use?

The Laser controller is built around the RP2040, from the RP2040/RP2350 family.

How big is the Laser controller PCB?

The Laser controller measures 30 × 109 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Laser controller?

124 components, from 43 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 Laser controller design files?

From the adeboni/eurorack 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 Laser controller design in my own project?

Yes, under the terms of its GPL-3.0 license, which adeboni chose for the repository.

Can I test firmware for the Laser controller 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.
