Mono Bluetooth 5.3 Amplifier Board

The ARRAROWN ZK-1001U is a mono amplifier board rated at 100W output for passive speakers between 20W and 100W with 3-8 ohm impedance. It integrates a TPA3116D2 chip delivering distortion below 0.3% and a Bluetooth 5.3 module supporting AAC decoding with low latency up to 15m range. The board accepts DC input from 9V to 24V, making it suitable for battery-powered outdoor speaker builds and home DIY audio projects.

Upgrading From Basic Amp Modules

This board replaces simpler amplifier modules that lack wireless connectivity or integrated voltage boosting. The jump is worth it when a project requires both Bluetooth 5.3 streaming with TWS stereo pairing capability and a built-in boost circuit that stabilises 9V or 15V input to 19V or 24V output via a selectable switch. It also adds USB flash drive and USB sound card inputs alongside the standard AUX connection for versatile source options.

Integration Into Speaker Builds

The compact board fits inside custom speaker enclosures and runs from 7.4V, 12V or 21V battery packs, though 24V batteries are not suitable. It requires a DC power source capable of at least 4A and cannot connect to AC mains. Two boards can be paired via the TWS box function to create a left-right stereo system from independent mono amplifiers. Treble and bass controls are provided for tone shaping directly on the module.

Questions about this item

What speaker impedance and power rating does the ZK-1001U mono board require?

Connect a passive speaker rated 20-100W with an impedance of 3-8 ohms. The TPA3116D2 chip delivers 100W rated power and distortion below .3% at that load.

Which input voltage range and boost setting should I select for a 12V battery?

Supply DC 9-24V at 4A or more; for a 12V battery leave the red switch at ON to boost to 19V. Do not connect AC and avoid 24V batteries.

How long will the Bluetooth 5.3 connection stay stable at distance?

The upgraded chip maintains low-latency AAC streaming up to 15m or 49ft from smartphones, tablets or laptops.
