Daakro ZK-1001U Bluetooth Amplifier Board

Daakro ZK-1001U is a compact stereo amplifier board pair that delivers up to 100W peak power, supports Bluetooth TWS pairing, and accepts USB, AUX and Bluetooth inputs for DIY home audio builds.

If you're building or upgrading bookshelf speakers, a compact soundbar, or a custom AV cabinet, the Daakro ZK-1001U amplifier modules offer flexible inputs, simple controls and a true wireless stereo (TWS) option so two identical boards form left/right channels without a wired link. Each module accepts a wide DC input range (9–24V), provides clear indicator lights, and includes multifunction knobs for volume, track control and power, making these boards suitable for hobbyist and semi-professional audio projects.

How do the two-module TWS features improve stereo sound?

Pairing two identical ZK-1001U modules in TWS mode assigns one board to the left channel and the other to the right, creating a realistic stereo image without running speaker wire between units. This is ideal for discrete speaker placement or modular setups.

• Wireless left/right separation via Bluetooth TWS pairing
• Improved soundstage when modules are spaced apart
• Easy reconfiguration: press the knob sequence to enter TWS mode

What input and playback options are available?

The ZK-1001U supports Bluetooth streaming, a 3.5mm AUX input and USB flash drive playback (also accepts USB sound card input), so you can connect phones, TVs, computers or play files directly from a drive. This range of inputs keeps the board compatible with most consumer devices.

• Bluetooth for wireless audio from phones and tablets
• AUX input for TVs, DACs or legacy sources
• USB port for flash drives and USB audio sources

What controls and status feedback does the board provide?

Each module includes a multi-function knob that controls volume, play/pause and track-skipping, plus power on/off with long press and a three-press shortcut to engage TWS. Two status LEDs clearly indicate power and TWS mode so you always know the board's state at a glance.

• Multi-function knob: volume, play/pause, track skip, power
• Red LED for power/operation status
• Blue LED indicates active TWS pairing

What power, installation and application details should I know?

The boards accept a wide voltage input (9–24V DC), which gives flexibility for popular adapters and battery packs. They are designed for DIY audio builds, home AV projects and small installations where compact size and versatile inputs matter. Proper ventilation and correct speaker matching will deliver the best performance.

• Wide voltage input (9–24V DC) for adapter or battery use
• Recommended for bookshelf, soundbar, and custom speaker enclosures
• Compact PCB footprint simplifies retrofits and new builds

Who is this for: The Daakro ZK-1001U pair suits DIY audio enthusiasts, hobbyists building compact stereo systems, makers adding wireless capability to passive speakers, and anyone needing a flexible amplifier board with multiple inputs and easy TWS stereo pairing. It's a practical choice when you need straightforward controls, clear status indicators, and a small, energy-efficient power amplifier for home or workshop projects.
