I’ve just released Bluepad32 v3.7.0 with two important features:
- Arduino IDE support
- In addition to ESP32, it also supports ESP32-S3 and ESP32-C3 (only BLE gamepads supported.)

Hi Ricardo,
we intyegrated your BluePad32 Arduino project in our Lego Mindstorms extenstion. This works great. We wrote a blog on our website: https://www.antonsmindstorms.com/2023/10/25/connect-gamepads-and-neopixels-to-your-lego-hub-with-ease-pupremote-tutorial/ and https://www.antonsmindstorms.com/2023/09/19/remote-control-lego-technic-hub-with-gamepad-ps4-sixaxis/
good to know that you found it useful. Thanks for the links!
