V3: common questions

What microcontroller does the V3 use?

The V3 is built around the RP2040, from the RP2040/RP2350 family.

How big is the V3 PCB?

The V3 measures 54.8 × 75.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the V3?

72 components, from 38 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 V3 design files?

From the atulravi/picuno 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 V3 design in my own project?

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

Can I test firmware for the V3 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.
