When Bluetooth-Compatible is connected, the indicator light is always on;
When Bluetooth-Compatible is playing, the indicator light flashes slowly.
MH-M18:
1.MUTE mute control terminal: used to control the power amplifier board. MUTE outputs a high level of 3.3V when muting and a low level when playing.
2. KEY button control: This function requires additional connection of resistors and buttons to be realized.
3. Volume retention function when power is off: default output volume. Use the buttons to control the volume increase or decrease.
4. Size: 23*16*5MM/0.91x0.63x0.2inch
MH-M28:
1. Power supply: You can directly use the MICRO USB Android cable 5V for power supply, or you can also connect an additional 5V power supply or 3.7V lithium battery.
2. Note that the power supply interfaces of 5V and 3.7V are different. The 5V voltage is connected to 5V and GND, and the 3.7V lithium battery is connected to VBAT and GND.
3. Audio output: The headset can be directly connected to the 3.5mm audio interface, or can be wired for the audio input of the power amplifier board
4. Size: 45*20*5MM/1.77x0.79x0.2inch
MH-M38:
1. Power supply: You can directly use the MICRO USB Android cable 5V for power supply, or you can also connect an additional 5V power supply or 3.7V lithium battery.
2. Note that the power supply interfaces of 5V and 3.7V are different. 5V is connected to 5V and GND, and the 3.7V lithium battery is connected to VBAT and GND.
3. The maximum working current is 5V2A. It is recommended to use a 5V2A regulated power supply.
4. Supports USB sound card, driver-free (plug and play). Use a USB data cable to connect the module to the computer. When the computer plays music, it can be output through the module amplifier.
5. Audio output: Output left and right channel stereo audio signals.
6. This product has its own dual 5W power amplifier circuit and cannot be used with another power amplifier. The outputs of the two power amplifiers cannot be connected in parallel or the negative poles are connected together, as this will damage the power amplifier chip.
7. Size: 45*20*5MM/1.77x0.79x0.2inch
Precautions
Signal interference: Bluetooth-Compatible antennas are extremely susceptible to interference from high-frequency or strong electromagnetic signals. Try to place them as far away from transmitting wireless devices as possible. And the board cannot be close to metal objects, keep a certain distance.
Since this product is designed as a bare board, try not to touch the components on the board with your hands, as static electricity may kill the chip and cause it to burn.
Warning: The charging interface of this product is in current-limiting charging mode and does not have charging management! For the safety of your life and property, be sure to use lithium batteries with protective plates produced by regular manufacturers.
Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
