Product details

Overview

The ARRAROWN ZK-1001U 2-pack Bluetooth 5.3 mono amplifier boards are crafted for ambitious DIY home and outdoor speaker projects. Each board delivers up to 100W into 3–8 ohm passive speakers, with an integrated boost circuit designed to help maintain stable voltage when used with battery-powered setups. The upgraded Bluetooth 5.3 module supports AAC decoding and provides a responsive wireless connection across typical room-to-yard ranges, enabling smoother streaming from mobile devices or tablets.

Built for flexibility, these mono amps support multiple inputs, including USB, AUX, and Bluetooth, offering versatile music sourcing for casual listening, small gatherings, or ambient sound. The two-pack configuration also enables TWS BOX mode, letting two units work together to realize left and right stereo from a single source, expanding the options for compact DIY systems.

Key capabilities

  • 100W per board with low distortion for clear, detailed audio across the full frequency range
  • Auto boost circuit that adapts input voltage to a stable 19V or 24V
  • TWS BOX compatibility to achieve stereo pairing between two mono amps
  • Bluetooth 5.3 with low latency for smoother wireless playback
  • Four input options: AUX, USB flash drive, USB sound card, and Bluetooth

Practical uses

  • Backyard parties or garden listening setups with battery powered speakers
  • DIY home audio projects or multi-room configurations using compact, modular amps
  • Portable sound for cabins, workshops, or patios where wired power is limited

Notes: This product is designed for compatible passive speakers in the 20–100W range with 3–8 ohms. It requires a DC power source within the 9–24V range and is not intended for AC mains connection.
