MH-M18 Bluetooth 4.2 Wireless Stereo Audio Receiver Module

The MH-M18 Bluetooth Audio Receiver Module is a compact wireless audio receiver board designed to add Bluetooth audio connectivity to DIY speakers, amplifiers, home audio systems, car audio projects, and other electronic projects. It allows you to stream audio wirelessly from Bluetooth-enabled devices such as smartphones, tablets, laptops, and other compatible audio sources.

The module supports Bluetooth 4.2 technology and provides two-channel stereo audio output for connection to an external audio amplifier. It can operate from a 3.7V–4.2V lithium battery supply or a 5V DC power source, making it suitable for a wide range of portable and DIY audio applications.

With its compact size and low power consumption, the MH-M18 is a convenient choice for upgrading existing audio equipment with wireless Bluetooth audio functionality. An external audio amplifier is required to drive speakers, as the MH-M18 is an audio receiver module and does not provide high-power speaker amplification.
