SplitFox: common questions

What microcontroller does the SplitFox use?

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

How big is the SplitFox PCB?

The SplitFox measures 255.8 × 122.5 mm, has 2 copper layers and is 1.2 mm thick.

How many components are on the SplitFox?

133 components, from 30 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 SplitFox design files?

From the speedypotato/SplitFox-Pro 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 SplitFox design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the SplitFox 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.
