Product Description
The MH-M28 Wireless Bluetooth Audio Receiver Module is a high-fidelity, low-power audio decoding board engineered to add wireless connectivity to any analog sound system. Unlike amplifier modules, the MH-M28 serves as a dedicated pre-amplifier receiver and lossless MP3 decoder, delivering a clean, unamplified line-level audio stream. Featuring optimized Bluetooth core architecture, it guarantees stable, long-range wireless streaming with minimal signal loss and ultra-low noise distortion.
For ultimate system integration, the module provides two convenient audio output methods simultaneously. Users can plug directly into the onboard gold-plated 3.5mm AUX headphone jack, or hardwire their downstream audio paths using the adjacent Left, Right, and Audio Ground (L, R, AGND) solder breakout pins. Powering the board is equally adaptive: it features a modern Type-C USB receptacle for a standard 5V supply, as well as dedicated top-side solder terminals for a 3.7V single-cell lithium-ion battery. This compact, versatile configuration makes it the perfect choice for upgrading legacy stereo amplifiers, retrofitting vintage home stereos, modifying car audio systems, or crafting custom wireless headphones.
