Reason ssl midi controller: common questions

What microcontroller does the Reason ssl midi controller use?

The Reason ssl midi controller is built around the Pico, from the RP2040/RP2350 family.

How big is the Reason ssl midi controller PCB?

The Reason ssl midi controller measures 122 × 124.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Reason ssl midi controller?

46 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the Reason ssl midi controller design files?

From the yves-obreykov/reason_ssl_midi_controller repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Reason ssl midi controller design in my own project?

Yes, under the terms of its MIT license, which yves-obreykov chose for the repository.

Can I test firmware for the Reason ssl midi 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.
