I need a bluetooth speaker for summer 2019...[edit] err no...rather 2021. I am building one with a twist. It must look like a M_rshall amp head, have a line-in connector and work on battery.
The TDA7492P board exists in several variation. Unfortunately, I did not spot that mine does not have a line-in connection. I had to fork the input directly from the board. I also heated the onboard leds and soldered wires so instead, I can use distant leds. So far so good, everything seems to work as expected. I will also do the same later with buttons....
