ARRAROWN ZK-1002T Bluetooth 5.0 Stereo Amplifier Board with Bass and Treble

Bluetooth 5.0, adjustable bass and treble, and a compact board design make the ARRAROWN ZK-1002T a practical way to add stereo amplification to a DIY audio setup. Connect a compatible source wirelessly or use an audio input, then adjust the sound and volume at the module to suit your speakers and listening space.

If you need a complete receiver with a built-in interface, that is a different approach, this board is for projects where a small, configurable amplifier module fits the plan. It supports 12–24V DC input and two-channel stereo output for compatible speakers.

Practical tips

Plan the power supply and speakers together: the module uses a 12–24V DC supply rated above 5A and is specified for 4–8Ω speakers rated 20–200W. Its listed output varies with supply voltage and speaker impedance, so use the matching figures below when planning your build. The connection labels are printed on the protective plate to make wiring easier to follow during installation.

For wireless listening, pair a phone, tablet, or other Bluetooth-enabled source with the module. Bluetooth 5.0 has a stated range of 15m/49ft. When switching to AUX, disconnect the module’s Bluetooth connection first. The board also lists USB audio input, giving DIY setups additional source options.

Benefits

Independent bass and treble controls let you shape the sound at the amplifier instead of relying only on adjustments at the source. Volume control is also built into the module, making it useful for compact speaker projects where direct access to basic adjustments matters. The TPA3116D2 amplifier chips and stated signal-to-noise ratio above 90dB are suited to a stereo DIY build, while the listed protection functions add safeguards during operation.

Buyers commonly praise the compact format, Bluetooth connection, and the ability to adjust volume and tone. Some also mention using the amplifier in boat-speaker and other custom speaker setups, those are examples of reported uses, not a substitute for matching speaker impedance and power ratings to the specifications.

When it makes sense

This board is a useful fit for a DIY stereo project that needs Bluetooth playback, physical bass and treble adjustment, and a small amplifier module rather than a full-size receiver. For example, a builder setting up a pair of compatible passive speakers can connect a phone wirelessly, adjust volume and tone at the board, and use the output figures to choose a suitable power supply and speaker pairing. Its compact footprint also helps when a project calls for a module that can be mounted within a custom audio build.

Worth considering if your project calls for two-channel amplification with flexible source inputs and hands-on sound adjustment. Match the DC supply and speakers to the specifications, and the ZK-1002T provides a clear, practical foundation for a compact DIY stereo system.
