I made an enclosure for the ESP-01 WLED shield, designed and created by Shields and More.

However, some people might still have this PCB in their collection, so I thought it would be fun to share my project. That way, others can benefit from it!

It’s a nice, compact enclosure with a fan inside to keep everything cool. You’ll need a few nuts, bolts, and inserts. Nothing too difficult for a tinkerer.

I showcased this project on the WLED Discord and received a tip that there’s an ESP32 variant in the same form factor as the ESP8266 ESP-01.

I know the ESP8266 is becoming a bit too small for the WLED firmware, but now there’s also an ESP32 version with the ESP-01 form factor. That was a nice surprise!
