About the Clicky PCB

Clicky is an open source RP2040/RP2350 PCB design by devoymac, published on GitHub. It is a 2-layer board measuring 117 × 63.4 mm, with 14 components from 4 distinct parts.

Its main chip is the XIAO-ESP32-C3-SMD, from the RP2040/RP2350 family. By type, the board carries 6 switches, 6 diodes, 1 IC and 1 connector.

It belongs with the power & battery, sensors and iot & wireless designs in this gallery.

From the project

A portable, battery-powered heart-shaped "pet" in the style of STΛRBOY / Lil Guy: a round animated eye, a personality driven by sensors, and a touch button to pet it — it blushes when you give it affection. It runs on a single LiPo battery and charges through the same USB-C port

A portable, battery-powered heart-shaped "pet" in the style of STΛRBOY / Lil Guy: a round animated eye, a personality driven by sensors, and a touch button to pet it — it blushes when you give it affection. It runs on a single LiPo battery and charges through the same USB-C port it uses to program.

Clicky is a small companion you wear on your clothes or bag. Inside a 3D-printed heart lives a round screen that acts as its eye, and a set of sensors give it a personality: it gets dizzy when you shake it, shivers when it's cold, startles at loud noises, and falls asleep if you ignore it. Touch…

Clicky: common questions

What microcontroller does the Clicky use?

The Clicky is built around the XIAO-ESP32-C3-SMD, from the RP2040/RP2350 family.

How big is the Clicky PCB?

The Clicky measures 117 × 63.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Clicky?

14 components, from 4 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 Clicky design files?

From the devoymac/clicky 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 Clicky design in my own project?

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

Can I test firmware for the Clicky 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.
