ZK-1002T Bluetooth 5.0 Amplifier Board 2.1 - Powerful DIY Stereo Amp

In this review the ZK-1002T Bluetooth 5.0 amplifier board is examined as a compact, DIY-friendly stereo amplifier for hobbyists and small home audio upgrades. The bottom line: it is best for builders who want a high-power, configurable module that pairs easily over Bluetooth and delivers substantial output using dual TPA3116D2 chips. The single biggest reason to buy is the combination of up to 100W per channel output and robust protection features, which make it suitable for driving 4-8 ohm, 20W-200W passive speakers while protecting the amplifier in real-world setups.

Key Features

• 100W x 2 output: Provides strong stereo power for bookshelf or small tower speakers and scales with higher supply voltage for more headroom.
• TPA3116D2 dual chips: The dual-chip design delivers cleaner HiFi sound with AM interference suppression for improved listening clarity.
• Bluetooth 5.0 wireless input: Offers stable wireless streaming with a reported barrier-free range up to 49 ft for convenience around a room.
• Wide supply range: Runs from DC 12-24V (5A recommended) so builders can choose power supplies to balance output and efficiency.
• Comprehensive protection: Built-in short circuit, thermal, over/under voltage and DC protection helps prevent catastrophic failure in DIY builds.
• Complete kit packaging: Ships with a protective shell, screwdriver and three control knobs to simplify installation into enclosures.

Who It's For

This board is aimed at DIY audio enthusiasts, hobbyists building custom powered speaker cabinets, and those upgrading older receivers with a compact high-power module. The flexibility of AUX plus Bluetooth and the compact 110mm x 70mm size make it a practical choice for small installations where space and power are constraints.

It is less suitable for users who need an integrated preamp with complex tone shaping, multi-zone routing, or digital inputs beyond Bluetooth and AUX. If you require factory-finished consumer electronics with guaranteed plug-and-play wall adapters included, a prebuilt amp or powered speaker may be a better fit.

Pros & Cons

Pros

• High output capability (100W per channel) suitable for driving a wide range of 4-8 ohm speakers.
• Bluetooth 5.0 gives a reliable wireless connection with useful range for room-scale use.
• Robust protection mechanisms reduce risk in DIY setups and protect the module under stress.
• Includes protective shell and controls so users can install it quickly into a custom enclosure.

Cons

• Power supply not included; achieving maximum performance requires an appropriate DC 12-24V, 5A+ supply which the buyer must source.
• No advanced digital inputs or integrated streaming services - limited to Bluetooth and AUX.
