About the PROJECT-CLICK PCB

PROJECT-CLICK is an open source RP2040/RP2350 PCB design by amionearth, published on GitHub. It is a 2-layer board measuring 100 × 80 mm, with 30 components from 6 distinct parts.

Its main chip is the XIAO-RP2040-DIP, from the RP2040/RP2350 family. By type, the board carries 21 diodes, 7 switches, 1 IC and 1 connector.

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

From the project

PROJECT-CLICK is a 3×2 matrix macropad with a cyberpunk-inspired design, built around the XIAO RP2040. I tried to make it look good as posible and it was my first build so it will have its own problems (the case is tight fit)

PROJECT-CLICK: common questions

What microcontroller does the PROJECT-CLICK use?

The PROJECT-CLICK is built around the XIAO-RP2040-DIP, from the RP2040/RP2350 family.

How big is the PROJECT-CLICK PCB?

The PROJECT-CLICK measures 100 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PROJECT-CLICK?

30 components, from 6 distinct parts. The full bill of materials is listed on this page.

Where can I download the PROJECT-CLICK design files?

From the amionearth/PROJECT-CLICK repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the PROJECT-CLICK design in my own project?

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

Can I test firmware for the PROJECT-CLICK 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.
