Testing the Second Board

A project log for Bluetooth CD Changer Emulator

In this project I reverse engineer the interface of my BMW CD changer and replace it by my own Bluetooth PCB to play music from my phone :).

As discussed in the previous log I removed the ESP32 Pico from my design and replaced it by a conventional ESP32 module. Because I was not yet able to do a lot of testing on my first design, the rest of the PCB remained unchanged. The good news is that thanks to the easier assembly of this second iteration I finally got a working board. So let's see what we can learn from further testing.
