About the Lightclock PCB

Lightclock is an open source RP2040/RP2350 PCB design by Anvarys, published on GitHub. It is a 2-layer board measuring 133 × 133 mm, with 191 components from 45 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the STP24DP05BTR, CH224K, TPS62160DGKR, SX3B12.000F1210F30 and W25Q64JVSSIQ. By type, the board carries 72 LEDs, 35 capacitors, 28 resistors, 12 ICs, 3 transistors and 2 diodes.

It belongs with the displays & leds and sensors designs in this gallery.

From the project

A custom PCB-based Clock/Alarm with a 3d printed enclosure. It features a runrise alarm option (72 LEDs), a 2.42" OLED display, many capacitive touch controls (24 around in a circle and 4 for the main controls) and a buzzer.

I made this project because I wanted to have a runrise alarm to wake up more naturally and also be easy to set up alarms with few clicks and without any additional installation required.

Lightclock: common questions

What microcontroller does the Lightclock use?

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

How big is the Lightclock PCB?

The Lightclock measures 133 × 133 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Lightclock?

191 components, from 45 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 Lightclock design files?

From the Anvarys/lightclock 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 Lightclock design in my own project?

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

Can I test firmware for the Lightclock 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.
