Bluetooth Amplifier Board 100W, with IPEX Antenna Connector (DC 9-24V) TPA3116 Mono Audio Amp, with TWS Pairing, AUX/USB/Bluetooth Input, Wired Volume Control for Speaker DIY, Car & Home Audio

[Stable Bluetooth 5.3 Connection with IPEX Antenna Support] Built-in Bluetooth 5.3 module combined with a 1st generation IPEX antenna connector lets you connect an external antenna (not included) for improved signal reception. Compared with standard onboard antennas, this design helps reduce interference and provides more reliable connectivity, especially in enclosed speaker boxes, metal cases, or car audio setups. [Up to 100W Mono Output with TPA3116 Chip] Powered by the widely used TPA3116 amplifier chip, this board delivers clear and stable mono audio output with low distortion. When paired with a suitable DC 9V24V power supply (not included), it can drive a wide range of DIY speaker projects while maintaining consistent sound performance.

[Wired External Volume Knob for Flexible Installation] Unlike traditional amplifier boards where the knob is fixed on the PCB, this design connects the potentiometer via wires, allowing you to freely position the volume control on your speaker enclosure or control panel. This makes installation cleaner, more convenient, and better suited for custom DIY builds. [TWS Pairing to Build a Stereo System] Supports TWS (True Wireless Stereo) function, allowing you to pair two amplifier boards wirelessly to create left and right channels. This makes it easy to upgrade from a single mono setup to a more immersive stereo system without complicated wiring.

[Multiple Audio Inputs for Versatile Use] Supports Bluetooth, AUX ( 3.5 mm), and USB input, giving you flexible options for different audio sources. Compatible with smartphones, tablets, PCs, and USB drives, making it suitable for DIY speakers, home audio systems, garage setups, or car audio projects
