Daakro ZK-1001B 100W Bluetooth Amplifier Board

Daakro ZK-1001B is a compact 100W mono Bluetooth amplifier board that supports TWS pairing, Bluetooth/USB/AUX inputs and runs on DC 7–24V for DIY wireless speakers and home AV projects.

Compact and versatile, this Daakro amplifier board is built for hobbyists and installers who want a password-free Bluetooth amp with multiple inputs and a simple pairing workflow. It delivers single-channel power suitable for bookshelf or custom speaker builds while offering TWS cabinet matching so two modules can form a stereo set without wiring. Controls are on-board with a multi-function knob and clear indicator LEDs for quick setup and reliable operation.

How does TWS pairing improve my DIY speaker setup?

TWS (True Wireless Stereo) lets two identical Daakro ZK-1001B modules pair so one unit handles the left channel and the other handles the right, creating a wireless stereo image. No speaker-level wiring between the two modules is necessary; simply place both units nearby for pairing and enjoy a more immersive soundstage.

• Wireless left/right channel separation with two identical modules
• Three-press knob shortcut enters TWS pairing mode
• No password required for fast, hassle-free pairing
• Improves stereo imaging for music and movies

What inputs and playback options are available?

The ZK-1001B supports four audio inputs so you can connect phones, TVs, computers or USB drives. Choose Bluetooth for wireless streaming, AUX for a wired source, USB flash drives for direct playback, or a USB sound card for computer audio routing.

• Bluetooth for wireless streaming from phones and tablets
• 3.5mm AUX input for TVs, DACs or legacy sources
• USB flash drive playback for MP3/WAV files
• USB sound card input for direct computer audio

Which controls and indicators make the board easy to use?

All key controls are integrated on the board through a single multi-function knob and two status LEDs. The knob adjusts volume, pauses/plays, advances tracks and powers the module on or off; two LEDs show device power/work status and TWS activity so you always know the module’s state at a glance.

• Multi-function knob: volume, play/pause, next-track, power on/off
• Press-and-hold to power on or off; triple click to start TWS mode
• WORK and TWS LEDs provide immediate status feedback
• Smooth knob action for precise volume control

What power and performance can I expect from a single board?

The ZK-1001B is rated as a 100W mono amplifier and accepts a wide DC input range of 7–24V to match various power supplies and battery setups. This flexibility makes it suitable for compact bookshelf speakers, active subwoofer builds, or portable systems when paired with the correct power source and speaker load.

• Rated up to 100W mono output (depends on supply voltage and speaker impedance)
• DC 7–24V input supports common SMPS and battery configurations
• Works with typical 4–8Ω speaker loads (check specifications for exact limits)
• Practical for home AV, DIY speakers, and portable audio projects

Who is this for? The Daakro ZK-1001B is designed for makers, audio DIYers and small installers who need a compact, feature-rich amplifier module that simplifies wireless stereo builds. It’s a good fit if you want multiple input options, straightforward on-board controls, and the ability to pair two units for stereo playback without running speaker cables. Ideal for bookshelf systems, custom enclosure projects, desktop audio, and lightweight portable rigs where reliable Bluetooth streaming and flexible power options are required.
