Mono 100W TWS Amplifier Board

The ZK-1001U is a mono Bluetooth amplifier board built around a TPA3116D2 chip, delivering 100W peak power for DIY speaker projects. It suits hobbyists and builders who need a compact, single-channel amp with wireless streaming and wired input flexibility.

Bluetooth 5.3 with Efficient Heat Dissipation

The board runs on a 9-24V supply and includes a built-in heat sink to manage thermals during extended use. Bluetooth 5.3 provides stable connections for streaming, while the mono design keeps power draw focused on a single output channel.

Compact Build with Three Input Options

The compact PCB integrates treble, bass and volume controls for on-board tuning without external pots. Bluetooth, USB and AUX inputs cover wireless streaming, local file playback and wired sources, while TWS pairing lets two boards form a stereo pair. Builders who need multi-channel amplification or rack-mount hardware should look elsewhere.

Questions about this item

How do I pair two ZK-1001U boards for TWS stereo?

Power both boards with no Bluetooth, USB or AUX connections active. Press and hold the microphone volume knob on one board for over one second; the red TWS indicator flashes while searching, then stays lit for the left channel or flashes for the right channel.

What maintenance will the TPA3116D2 amplifier need over time?

The built-in heat sink handles thermal dissipation; keep ventilation openings clear of dust and ensure the 9-24 V supply stays within range so the chip does not overheat during extended use.

At what input voltage does the boost circuit reach its limit during sustained high-power output?

The board accepts 9-24 V; at the lower end of this range the boost converter works hardest, so prolonged 100 W mono output is most constrained when the supply is near 9 V.
