Description:
This product mh-m18 /M28/M38 is a low power bluetooth design scheme, support the latest bluetooth 4.2 transmission, dual sound channel stereo lossless playback, module connected to bluetooth, you can quickly achieve bluetooth wireless transmission, very convenient.
Open environment, bluetooth connection distance up to 20 meters.
Widely used in all kinds of bluetooth audio reception, all kinds of audio DIY modification.
Function declaration:
1. Bluetooth V4.2 version, support bluetooth automatic connect
technology, support WAV/WMA/FLAC/APE/MP3 lossless decoding, stereo dual channel output.
2. After the module is powered on, the phone searches for the bluetooth
name mh-m18 / mh-m28 / mh-m38. After connecting the bluetooth, music can be played.
Module blue indicator light:
3. Module blue indicator light:
The indicator flashes when the bluetooth is not connected
The indicator light is always on when the bluetooth is connected；
The indicator light flashes slowly while the bluetooth is playing.
SIZE:M18:22.8mm*16mm M28:45.2mm*20.2mm M38:45mm*20.3mm
Note:
1. Signal interference: bluetooth antenna is very vulnerable to high frequency or strong electromagnetic signal interference, as far
as possible away from the sending wireless devices and other places. And the board should not be close to the metal objects, keep a certain distance.
2. If there is current sound on the receiving power amplifier board, which is caused by ground wire interference, it is suggested that the output end of
Bluetooth module should not use plug wire, welding wire is necessary, especially the ground wire to be welded, and the wire should not be
too long, the shorter the better, as thick as possible. The problem of audio ground at the receiving point of the power amplifier board must be at
the receiving point of the audio input of the power amplifier. It is recommended that the bluetooth and power amplifier board be separately powered, isolating the bluetooth
ground and power amplifier ground.
3. As this product is designed for bare board, try not to touch the components on the board with your hands, which may easily lead to electrostatic killing and chip burning.
Warning: the charging interface of this product is current limited charging mode, without charging management! For the safety of your life and property, please be sure to use the lithium battery with protection plate produced by the regular manufacturer.
In addition, the following two points should be paid attention to when using mh-m18:
Power supply: 5V power supply by default. If the 3.7v lithium battery is needed for power supply, it is necessary to replace the diode with 0603 ohm resistor, or simply short out the ends of the solder pad.
Bluetooth audio module has very high requirements on power supply, which will affect the audio quality. It is recommended to add LC filter circuit, especially the power supply of switching power
