Two small green circuit boards with silver heatsinks, knobs and 3.5mm jacks

ZK-1001U 2Pcs Mono Amplifier Board 100W Bluetooth 5.3

SKU CH-GK2K-0CSKE

Two mono amplifier boards deliver 100 W each via TPA3116D2 chips with Bluetooth 5.3, USB, AUX, treble/bass controls and TWS stereo pairing from 9–24 V DC

  • 100 W mono output per board drives DIY speakers with authority
  • Built-in boost circuit lifts 9 V or 15 V input to stable 19 V or 24 V for consistent performance
  • Bluetooth 5.3 plus USB and 3.5 mm AUX inputs cover wireless, flash-drive and wired sources
  • TWS pairing links two boards wirelessly for true stereo separation
  • Treble and bass knobs plus multifunction rotary control let you shape sound and manage playback

Two-Channel DIY Audio Kit

This pack contains two ZK-1001U mono amplifier boards built around the TPA3116D2 chip. Each module delivers 100W output and accepts a 9-24V DC supply. Bluetooth 5.3, 3.5mm AUX and USB inputs let you stream wirelessly, play from a FAT32 flash drive up to 32GB or connect a wired source. A built-in boost circuit lifts lower voltages to a stable 19V or 24V rail.

Makers Building Portable Stereo Pairs

The TWS function links the two boards wirelessly for left and right channels without an interconnect cable. Treble and bass controls plus a multi-function knob handle volume, playback and pairing. Buyers who need a single finished amplifier with a case, power supply or speaker terminals should look elsewhere. Anyone requiring more than two channels or a different chip architecture will not be served by this kit.

Drop-In Modules for Custom Enclosures

Each board runs from a 9-24V source such as a battery pack or desktop adapter, freeing the builder from mains wiring inside the cabinet. The auto-boost stage keeps output steady when the supply sags. USB playback supports FAT32 drives up to 32GB. The compact footprint leaves room for crossover components, binding posts and the chosen drivers inside the same enclosure.

Questions about this item

What power source is needed to run the ZK-1001U mono amplifier board?

The board accepts a DC input between 9 V and 24 V; its built-in boost circuit lifts 9 V or 15 V supplies to a stable 19 V or 24 V (default 24 V) for full 100 W output.

Can I keep my existing 3.5 mm AUX source and still use Bluetooth 5.3 streaming?

Yes — the module provides Bluetooth 5.3, USB sound-card/flash-drive playback and a 3.5 mm AUX input simultaneously; you select the active source with the multifunction knob.

How do I confirm the two boards are paired in TWS stereo mode after power-up?

Double-click the knob on either board; the modules enter TWS pairing automatically and an audible prompt sounds when the left/right link is established.
