Crossfire: common questions

What microcontroller does the Crossfire use?

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

How big is the Crossfire PCB?

The Crossfire measures 140 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Crossfire?

61 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the Crossfire design files?

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

Can I use the Crossfire design in my own project?

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

Can I test firmware for the Crossfire 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.
