Lucenox is an open source RP2040/RP2350 PCB design by lumentae, published on GitHub under the MIT license. It is a 4-layer board measuring 348.5 × 118 mm, with 253 components from 87 distinct parts.

Its main chip is the RaspberryPi_Pico, from the RP2040/RP2350 family. By type, the board carries 84 LEDs, 84 diodes and 1 module.

It belongs with the keyboards designs in this gallery.

From the project

A keyboard for Hackclub's Highway

Lucenox is a custom mechanical keyboard with hotswappable switches which was inspired by the QWERTZ layout. It also features per key RGB with QMK!

I made the project just for fun and to see if I could build my own keyboard, because I wanted something that felt exactly like my current keyboard, but in a smaller size. Also I currently use a membrane keyboard and I thought that highway could give me an opportunity to learn how mechanical keyboards work and switch to a mechanical one.

Lucenox: common questions

What microcontroller does the Lucenox use?

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

How big is the Lucenox PCB?

The Lucenox measures 348.5 × 118 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Lucenox?

253 components, from 87 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 Lucenox design files?

From the lumentae/lucenox 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 Lucenox design in my own project?

Yes, under the terms of its MIT license, which lumentae chose for the repository.

Can I test firmware for the Lucenox 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.
