The KiCad project lives in the Charles-D-FPU/Lights-out-Matrix repository on GitHub; these links point at the commit this page was built from.

Lights out-Matrix: common questions

What microcontroller does the Lights out-Matrix use?

The Lights out-Matrix is built around the RaspberryPi_Pico, from the RP2040/RP2350 family.

How big is the Lights out-Matrix PCB?

The Lights out-Matrix measures 87 × 137.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Lights out-Matrix?

111 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the Lights out-Matrix design files?

From the Charles-D-FPU/Lights-out-Matrix repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Lights out-Matrix design in my own project?

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

Can I test firmware for the Lights out-Matrix 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.
