esp32 Macro Key Pad with Bluetooth

Version 2 Used in pictures

A compact 19-key Bluetooth macro pad. Supports standard mechanical switches. Perfect for macros, shortcuts or creative workflows. Ideal for DIY keyboard enthusiasts and fully customizable to fit your setup.


Version 1 has the ESP mounted directly at the outer edge with the soldered USB-C port for flashing, and the second version uses a separate USB-C connector. Since I was too lazy to design a proper mount for the ESP you’ll need to glue it in place—so I recommend using version 2.

I simply downloaded my keycaps from Thingiverse—feel free to choose any that you like.

Each switch is connected to ground through the wire grid that I soldered, and also to a separate data pin on the ESP32.

i used switches from an old broken keyboard.
