Two 128x64px LED panels looping animated gifs. Powered by an ESP32 and a custom PCB!
- Yes, he’s built using “Arduino”! No, it’s not Neopixel LEDs! Yes, he is adorable!
- Furret uses a custom PCB I designed to drive HUB75 panels with an ESP32!
- The LED panels were $25 each and the microcontroller was $5. It’s powered by a USB battery pack!
- The original pixel art animation was done by the extremely talented Alex Illustration! My wife and I modified the basic animation in Photoshop to make all the other animations!

This repository isn’t meant to be a good sample project, it’s just my personal project. It was built on top of so many incredible libraries:
We used Photoshop to create the animations!
- PCB I designed to drive HUB75 panels with an ESP32: Buy on Tindie!
- This part is optional, but greatly simplifies your wiring!
- ESP32-DEVKIT-V1: Amazon ($14 for 2)
- You can use a different ESP32 if you don’t use my PCB. Just remember to verify it has the required pins mentioned below!
- 128x64px, P2.5, 1/32, HUB75E purchased on AliExpress
- Bubble machine extracted from children’s bubble wand toy, purchased on eBay
I butchered a USB cable to supply the 5V power from a large USB battery bank. At full brightness, one panel pulls about 2 amps @ 5 volts. Since the displays are so hungry, I recommend running the ESP32 from a separate 5V power source to avoid brownouts due to voltage sag.
