Vbox mobo: common questions

What microcontroller does the Vbox mobo use?

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

How big is the Vbox mobo PCB?

The Vbox mobo measures 33.1 × 114.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Vbox mobo?

63 components, from 19 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 Vbox mobo design files?

From the CarVac/vbox 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 Vbox mobo design in my own project?

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

Can I test firmware for the Vbox mobo 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.
