Synthesizer: common questions

What microcontroller does the Synthesizer use?

The Synthesizer is built around the RaspberryPi_Pico, from the RP2040/RP2350 family.

How big is the Synthesizer PCB?

The Synthesizer measures 29.5 × 88.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Synthesizer?

22 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the Synthesizer design files?

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

Can I use the Synthesizer design in my own project?

The repository has no license, so all rights stay with A-Louarn. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Synthesizer 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.
