The KiCad project lives in the jguillen-lab/BFS9000 repository on GitHub; these links point at the commit this page was built from.

BFS9000: common questions

What microcontroller does the BFS9000 use?

The BFS9000 is built around the RP2040 Core board, from the RP2040/RP2350 family.

How big is the BFS9000 PCB?

The BFS9000 measures 252.5 × 149.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BFS9000?

233 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the BFS9000 design files?

From the jguillen-lab/BFS9000 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the BFS9000 design in my own project?

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

Can I test firmware for the BFS9000 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.
