Aideepen 100W Mono Bluetooth Amplifier Board ZK-1001U

The Aideepen ZK-1001U is a compact 100W mono Bluetooth amplifier board built for DIY car and home speaker projects, offering TWS stereo pairing, wide 9–24V input, and multiple wired/wireless inputs.

This single-board amplifier combines the TPA3116 power stage with an upgraded Bluetooth 5.3 module to deliver a flexible, high-power platform for makers and audiophiles building custom speakers or upgrading in-car audio. Its compact footprint, on-board boost circuit, and manual voltage switch let you run reliably from batteries or vehicle power while tuning sound with dedicated tone controls.

How does the ZK-1001U handle different power sources and voltages?

The board accepts a wide 9–24V input and uses a built-in intelligent boost circuit to regulate voltage for stable amplifier operation. A red mode switch allows manual selection between two boosted voltage defaults, so you can match output to speaker needs and battery configurations.

• Wide input range: 9–24V for cars, batteries, and many adapters
• Automatic boost to stable 19V or 24V for consistent performance
• Manual red switch toggles boost output for speaker matching
• Additional power cable included for easier battery connections

What audio inputs and controls are available?

The board supports Bluetooth, USB flash drive playback, USB sound card input, and a 3.5mm AUX line-in to connect phones, PCs, or MP3 players. The front panel includes three knobs for treble, bass, and multifunction control with simple tap commands for play/pause, track skip, power, and TWS pairing.

• Bluetooth 5.3 with AAC decoding for wireless streaming
• USB flash drive and USB sound card support for direct digital input
• 3.5mm AUX input for analog sources
• Multifunction knob: long press power, click play/pause, double-click next, triple-click TWS

Can I create stereo sound using this mono amplifier?

Yes — the ZK-1001U supports one-click TWS pairing to sync two identical boards wirelessly and form true left/right stereo channels. This makes it straightforward to build a pair of portable wireless speakers or a compact stereo system without running speaker wires between amplifiers.

• TWS box mode for wireless left/right synchronization
• Low-latency Bluetooth connection suitable for music playback
• Ideal for DIY stereo speaker pairs and party systems
• Supports high-fidelity playback for improved audio detail

What performance and reliability features are built in?

The amplifier uses a genuine TPA3116 mono chip known for efficient Class-D operation, and an intelligent boost circuit to maintain stable output. The board is optimized for outdoor battery-powered builds as well as vehicle installations, and the component layout supports heat dissipation for sustained use.

• Authentic TPA3116 amplifier IC for efficient 100W output
• Intelligent boost circuit for voltage stability under load
• Compact PCB layout allowing DIY integration into enclosures
• Practical accessories included for battery-powered projects

Who is this for? The Aideepen ZK-1001U is aimed at hobbyists, makers, and small-scale audio builders who want a powerful, compact amplifier board that handles battery or vehicle power, supports multiple input types, and can be paired wirelessly for stereo. It’s a solid choice for custom car audio projects, portable speaker builds, workshop systems, and anyone seeking a flexible high-power mono amp to form the backbone of a DIY stereo setup.
