Wireless alternative to ATMEGA32U4 (noob here)

Other Hardware 3rd Party Boards

Guys, I'm trying do build a custom keyboard, and for that I'm following this tutorial to create a PCB:

But I really want to build a wireless keyboard, and the ATMEGA32U4 that the tutorial requires uses USB.

As a noob with eletronics that doesn't even what terms to user search an alternative to ATMEGA32U4.

I want to build a PCB to build a abnt2 keyboard with TKL(80%) size. Actually I have searched a lot, and does't find anywhere this device to buy, so I'll try to build it myself.

PS: I probably will use the ATMEGA32U4 first, then I'll change it to some wireless alternative.

Thanks for your time.

I would start by going through several basic electronics and Arduino tutorials on line. If you can swing it the Arduino Bible (Arduino Cookbook) is a tremendous wealth of information with great explanations of how things work. Also look at the ESP parts such as the ESP8266 and the ESP32.

Thanks. You helped me a lot with this answer, now it was a little bit clear where I can search this kind of thing.

I think you could have success with an ESP32 acting as a BLE HID.

This ESP32 Mouse/Keyboard for BLE HID has a lot of stars.
