Product description
This amplifier module with the TPA3116 chip is a component-level solution for wireless audio amplification. It receives audio signals via Bluetooth 5.0 and directly drives speakers up to their rated power, without requiring additional audio preamps.
The amplifier runs on 24 V DC and delivers up to 100 W of combined power (50 W per channel) into 4-ohm loads, or up to 200 W (100 W per channel) into 2-ohm loads. The operating voltage is fixed at this value; operation at other voltages is not supported. Pairing with Bluetooth sources uses the aptX codec standard, designed for low latency in wireless transmission.
Typical applications include building portable or stationary Bluetooth speakers, adding Bluetooth connectivity to passive speaker systems, or repairing and upgrading older audio devices with Bluetooth. The compact design fits into small enclosures. One possible application is a DIY party box with two or more of these modules for multichannel operation in a custom wooden enclosure.
Since the module is supplied without connectors, all connections (power supply, speakers, optional audio input) must be soldered. A 24 V power supply with sufficient current for the desired output must be obtained separately. A lab power supply or industrial-grade power supply is typically used with a board that has no power supply.
Safety notice
The module is not intended for installation in household electrical systems and is designed exclusively for building prototypes and for testing and development purposes. The 24 V power supply must have adequately rated protection (fuse or circuit breaker) to protect the module from damage in the event of a fault. If you are unsure about the power supply or speaker matching, consult a qualified electrician.
