Wideband v3: common questions

What microcontroller does the Wideband v3 use?

The Wideband v3 is built around the RP2040, from the RP2040/RP2350 family.

How big is the Wideband v3 PCB?

The Wideband v3 measures 80 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Wideband v3?

58 components, from 29 distinct parts. The full bill of materials is listed on this page.

Where can I download the Wideband v3 design files?

From the Churrosoft/OpenEFI-Wideband repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Wideband v3 design in my own project?

Yes, under the terms of its MIT license, which Churrosoft chose for the repository.

Can I test firmware for the Wideband 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.
