Wavetable hardware pcb 2 rev1: common questions

What microcontroller does the Wavetable hardware pcb 2 rev1 use?

The Wavetable hardware pcb 2 rev1 is built around the XIAO-RP2040, from the RP2040/RP2350 family.

How big is the Wavetable hardware pcb 2 rev1?

The Wavetable hardware pcb 2 rev1 measures 40.6 × 128.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Wavetable hardware pcb 2 rev1?

95 components, from 44 distinct parts. The full bill of materials is listed on this page.

Where can I download the Wavetable hardware pcb 2 rev1 design files?

From the szegedylorant/wavetable-vco repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Wavetable hardware pcb 2 rev1 design in my own project?
