Music Streaming Amp (And no Sonos to ruin it)
August 11, 2026
Possibly my favourite ever ESP32 product/project, the LouderESP32! These boards are cheap, but pack a powerful punch in the audio department, but lack USB-PD input. While I was adding that, I threw in some LEDs and a volume knob.
I’m using a LouderESP32 (duh), and the Sendspin firmware (with a few modifications), powered by Music Assistant to stream to it over the network.
