Digital Bluetooth Power Amplifier (50W*2)
Discontinued
A dual-channel digital power amplifier board with built-in Bluetooth 5.0 connectivity. Each channel delivers up to 50W of output power, making it a versatile choice for DIY speaker builds, Raspberry Pi audio projects, and custom sound systems. The board also supports playback from TF cards and USB drives.
Onboard function buttons let you switch playback modes, control volume, skip tracks, and adjust EQ settings without needing a separate controller. A USB-C connection is included for playing audio directly from a laptop.
