V2: common questions

What microcontroller does the V2 use?

The V2 is built around the TLV70033DDCR, from the RP2040/RP2350 family.

How big is the V2 PCB?

The V2 measures 178.7 × 150.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the V2?

102 components, from 10 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 GearBoxFox/foxxboard 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 GearBoxFox. 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.
