An interactive, cute desktop companion powered by a Seeed Studio XIAO RP2040 microcontroller!

CyberPet lives on your desk and reacts to its environment in real time: pet it to see it happy, or turn off the room lights to let it fall asleep!

Interactive Touch Control: Built-in capacitive touch sensor (TTP223) detects when you pet CyberPet, triggering happy facial expressions and sound effects. Day/Night Cycle Sensing: Uses a photoresistor (LDR) light sensor circuit to detect when the lights go out, automatically putting the pet to sleep (Zzz). Expressive Display: 0.91" I2C OLED display…

Cyber-Pet: common questions

What microcontroller does the Cyber-Pet use?

The Cyber-Pet is built around the XIAO-RP2040-DIP, from the RP2040/RP2350 family.

How big is the Cyber-Pet PCB?

The Cyber-Pet measures 44.6 × 44.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Cyber-Pet?

6 components, from 6 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 Cyber-Pet design files?

From the yansha2903-bot/Cyber-Pet 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 Cyber-Pet design in my own project?

The repository has no license, so all rights stay with yansha2903-bot. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Cyber-Pet 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.
