Mono 100 W Amplifier Board

The Daakro ZK-1001U is a mono Class-D amplifier board rated for 100 W peak output from a single TPA3116D2 chip. It accepts a wide DC input range of 7–24 V through a 5.5 mm × 2.1 mm jack, making it suitable for vehicle systems or bench supplies. Bluetooth, AUX and USB flash-drive inputs are provided for source flexibility.

DIY Builders Seeking Wireless Mono Power

Makers assembling a single powered speaker, a subwoofer module or a portable Bluetooth boombox will find the board a compact, self-contained solution. Installers needing stereo output, multi-channel surround or rack-mountable home-theatre amplification should look at alternative designs.

4–8 Ω Output Impedance Match

The module is specified for 4–8 Ω speaker loads; connecting a lower-impedance driver will trigger the built-in short-circuit and over-temperature protection. Verify that your speaker falls within this range before wiring the output terminals.

Questions about this item

Does the Bluetooth interface limit audio quality compared to wired AUX?

Bluetooth and AUX inputs both feed the same TPA3116D2 chip, so the amplifier’s 100 W peak output is available regardless of which source you select.

What voltage and connector does the board need for power?

It accepts DC 7 V to 24 V through a 5.5 mm × 2.1 mm barrel jack, compatible with most laptop power adapters.

How do I pair two boards for stereo, and what is the common mistake?

Press the knob three times on each board to enter TWS mode; the mistake is pressing only once, which only toggles play/pause instead of starting the pairing handshake.
