Pocket Remote v1

Pocket Remote v1 is an open-source universal infrared remote built around the ESP32 platform.

It allows users to learn, store, organize and transmit infrared signals from almost any IR-controlled device while remaining fully portable thanks to its rechargeable Li-Po battery.

The project was designed to be inexpensive, easy to build and completely open source.
