Hilitand TPA3110 2x15W Bluetooth Audio Amplifier Board - Compact

In this review of the Hilitand TPA3110 2x15W Bluetooth Audio Power Amplifier Board, the bottom line is simple: it is a compact, capable stereo amp board best suited to DIY audio projects and small speaker builds that need clean digital amplification with Bluetooth input. The reviewer found the module delivers noticeably better performance than typical analog hobby amps, with low distortion and reliable Bluetooth reception up to about 10 meters. Its small 58 x 38 x 10mm footprint and 10-25V input range make it easy to integrate into custom enclosures or desktop speaker projects.

Key Features

• Digital amplifier: The TPA3110 design provides higher overload capacity and avoids crossover and transient intermodulation distortion for clearer sound at moderate volumes.
• Bluetooth input: The built-in Bluetooth receiver accepts wireless audio from phones or computers and works reliably within the specified 10 meter maximum distance.
• Dual-channel output: With 15W+15W output the board powers small stereo speakers and supports a range of speaker impedances for flexible use.
• Wide input voltage: The 10 to 25V DC input range (12V recommended) gives options for battery or desktop power supplies without special converters.
• Compact size: At 58 x 38 x 10mm the module is easy to mount in tight spaces for DIY audio enclosures or repairs.
• Speaker compatibility: Designed for 4, 6, 8 and 10 ohm speakers so it can drive common small speaker loads.

Who It's For

This board is ideal for hobbyists building bookshelf or desktop speakers, makers adding Bluetooth to an existing amp, and anyone assembling a compact stereo system where space is limited. The module's digital amplifier and dual-channel outputs make it a straightforward choice for clear, distortion-resistant audio at household listening levels.

It is not aimed at high-power home theater systems or large PA speakers; users needing many tens or hundreds of watts per channel should look for a higher-power amplifier. Also, those who want built-in tone controls or multiple inputs will need additional components or a different product.

Pros & Cons

Pros

• Clean digital output with reduced distortion compared with basic analog modules.
• Convenient Bluetooth input for wireless streaming without extra receivers.
• Flexible power input from 10 to 25V DC, with 12V recommended for typical use.
• Compact footprint makes it easy to integrate into DIY enclosures.

Cons

• Limited to 15W per channel, so it is not suitable for large or high-power speaker systems.
• No onboard EQ or multiple wired input options beyond Bluetooth.
