Lights: common questions

What microcontroller does the Lights use?

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

How big is the Lights PCB?

The Lights measures 52.5 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Lights?

57 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 Lights design files?

From the QuinnFreedman/modular 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 Lights design in my own project?

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

Can I test firmware for the Lights 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.
