V2: common questions

What microcontroller does the V2 use?

The V2 is built around the Pico, from the RP2040/RP2350 family.

How big is the V2 PCB?

The V2 measures 91.9 × 55.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the V2?

18 components, from 15 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 V2 design files?

From the ambadran/Free-Lance-Projects 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 V2 design in my own project?

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

Can I test firmware for the V2 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.
