    Bluetooth Audio for Arduino

  • Hands-free calling would definitely be possible with the ESP32, but the audio library I use doesn't currently support it. https://github.com/tierneytim/btAudio/issues/20 If you want to get your hands dirty, feel free to jump in and see if you can get HFP working ;)

  • GM-EandC-Cemu-v2

    GM E&C bus cassette deck emulator

  • Attach female connectors to the two thick wires of the UBEC, and 4 more wires (just snip off the ends of some jumpers and strip the wires). Pick any color you want for the 4 wires as long as they don't overlap with each other or the black/red wires from the UBEC. Once the female headers are on, insert them into the plastic connector, using this as your guide: https://github.com/qwertychouskie/GM-EandC-Cemu-v2/blob/master/Documentation/9pin_connector_pinout.gif

  • WorkOS
