MakerHawk Bluetooth Amplifier Board HiFi Stereo 2.1 - Compact Power

In this review the MakerHawk Bluetooth Amplifier Board HiFi Stereo 2.1 is assessed for DIY audio builders and small home theater setups; the single biggest reason to buy is its combination of Class D TPA3116D2 performance and flexible inputs, delivering up to 2x50W for satellites plus 100W for a sub when powered correctly. The board's Bluetooth 5.0 and AUX inputs make it a practical 2-in-1 option for retrofitting older speakers or driving a compact 2.1 system, and the included shell and wiring hardware make initial installation straightforward for users comfortable with wiring and simple solderless terminals.

Key Features

• High fidelity Class D amp: The TPA3116D2 chip provides efficient, low-distortion amplification suitable for clear music playback at moderate volumes.
• Dual inputs: Bluetooth 5.0 plus AUX input allow wireless streaming or direct wired connection for flexible source options.
• 2.1 channel outputs: Delivers separate left/right channels and a driven subwoofer channel to support a full small home theater or desktop setup.
• Protection mechanisms: Built-in short-circuit, thermal, overvoltage, undervoltage and DC detection protect the board and connected speakers during faults.
• Robust connectors: Copper DC connector and fence type terminal tolerate higher currents and simplify wiring without heat damage to leads.
• Tone controls: Bass, treble and volume knobs offer quick on-board adjustment to tailor sound without extra equalizers.

Who It's For

This board suits DIY enthusiasts rebuilding old speaker systems, makers creating compact home theater or store playback systems, and anyone who needs a modest but punchy 2.1 amplifier with modern Bluetooth streaming. It is especially useful when paired with a decent power supply (12-24V, 5A or above) and speakers rated around 20-100W and 4-8 ohm impedance.

Those who should look elsewhere include buyers seeking a plug-and-play finished receiver with extensive room correction or consumers who need guaranteed long-term reliability without occasional Bluetooth quirks; some users report mixed Bluetooth behavior and variable unit lifespans, so commercial installers may prefer a proven sealed unit.

Pros & Cons

Use a stable 12-24V DC supply rated at 5A or higher to reach the board's rated outputs and avoid undervoltage protection triggers.

Can it drive a passive subwoofer?
Yes; the board includes a dedicated subwoofer output rated up to 100W provided the sub impedance and power supply match the specification.

Is Bluetooth easily disabled?
Bluetooth is available for wireless sources, but some users report they cannot fully disable the Bluetooth receiver on certain units, so expect it to be active unless you physically modify or mute the module.
