I have a Muse Lux speaker which came with the Micro USB port, unfortunately over time this port has become damaged and came off the PCB, I’d like to reprogram the ESP module on it so was wondering if there is a circuit diagram to show where I could connect the serial ports up to reflash the board? I’m quite a novice when it comes to soldering but I’m quite keen to try and get this speaker connected back to home assistant.
Attached is the damage where the microUSB port was.
hi, it seems difficult to repare and without usb port it will be impossible to charge / power the device.
To reprogram it you can just solder wire on the RX TX pin of the ESP32 Wrover module (any smart AI will guide you step by step).
Good luck
