Product Description
The MH-M18 Wireless Bluetooth 4.2 Audio Receiver Module is an ultra-miniature, high-fidelity audio decoding board engineered to add seamless wireless connectivity to custom sound systems. Operating as a highly efficient pre-amplifier line-level receiver, this module decodes high-resolution, lossless wireless audio streams with incredible clarity, low noise distortion, and excellent transmission range. Its bare-board micro footprint is intentionally streamlined to strip away unnecessary weight and bulky connectors, allowing it to drop easily into tight physical spaces.
The module features a single-row pinout interface that guarantees clean wiring routing. The pinout structure includes dedicated solder pads for power (VCC and GND), independent line-level Left and Right stereo channel outputs (L and R), a dedicated MUTE control line for silencing downstream amplifiers during disconnects, and an external KEY pad to support custom button control arrays (such as volume adjustments or track skipping). This highly adaptive, component-level design makes the MH-M18 the ultimate choice for engineers, makers, and DIY hobbyists looking to embed wireless audio directly into power amplifier boards, custom Bluetooth speakers, active desktop monitors, or retrofitted car stereo head units.
