Rev3 design files

The KiCad project lives in the MrFriedOk/flickerflame repository on GitHub; these links point at the commit this page was built from.

Rev3: common questions

What microcontroller does the Rev3 use?

The Rev3 is built around the RP2040, from the RP2040/RP2350 family.

How big is the Rev3 PCB?

The Rev3 measures 47.6 × 76.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rev3?

56 components, from 24 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 Rev3 design files?

From the MrFriedOk/flickerflame 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 Rev3 design in my own project?

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

Can I test firmware for the Rev3 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.
