Reminder: The M28 version is connected to the audio output of the power amplifier board, earphones, active speakers, etc., and the M38 version can only be connected to two 3-5W speakers!
New product version 5.0! Backward compatible with 4.2 4.1 4.0
Product introduction:
This product MH-M28/M38 is a low-power Bluetooth design scheme, supports the latest Bluetooth 5.0 transmission, two-channel stereo lossless playback, after the module is connected to Bluetooth, Bluetooth wireless transmission can be quickly realized, which is very convenient. In an open environment, the Bluetooth connection distance can reach up to 20 meters.
It is widely used in various Bluetooth audio receivers, various audio DIY modification, etc.
For the different needs of customers, we provide 2 versions for you to choose:
1. Bluetooth V5.0 version, support Bluetooth automatic connection technology, support WAV/WMA/FLAC/APE/MP3 lossless decoding, stereo dual-channel output.
2. After the module is powered on, the mobile phone searches for the Bluetooth name MH-M28/MH-M38, and it can play music after connecting to the Bluetooth;
3. Module blue indicator light:
When Bluetooth is not connected, the indicator light flashes quickly;
When the Bluetooth is connected, the indicator light is always on;
When Bluetooth is playing, the indicator light flashes slowly.
M18:
The module interface adopts a half-hole process, and customers can directly mount or weld on the board.

AGND》audio ground
1. Power supply: You can directly use the MICRO USB Android cable 5V for power supply, or you can also connect to a 5V power supply or a 3.7V lithium battery. Note that the 5V and 3.7V power supply interfaces are different. The 5V voltage is connected to 5V and GND, and the 3.7V lithium battery is connected to VBAT and GND.
2. Audio output: The earphone can be directly connected to the 3.5mm audio interface, or it can be wired for the audio input of the power amplifier board (L/R/AGND shown on the circuit board can be directly wired).

Note that the power supply interface of 5V and 3.7V is different, 5V is connected to 5V and GND, and 3.7V lithium battery is connected to VBAT and GND.
The maximum working current is 5V2A. It is recommended to use a 5V2A regulated power supply for better sound quality.
2. Support USB sound card, free drive (plug and play). Connect the module to the computer with a USB data cable, and the computer can play music and output through the module's amplifier
3. Audio output: output left and right channel stereo audio signals, which can be connected to two 2-8 ohm and 3-5W speakers respectively, and 4 ohm 5W speakers are recommended for storage.
4. This product has built-in dual 5W power amplifier circuit, it must not be used with another power amplifier! The outputs of the two power amplifiers cannot be connected in parallel or the negative poles connected together, otherwise the power amplifier chip will be damaged.
