Product description: Bluetooth 5.0 Digital Amplifier Module - DFRobot DFR0675-EN
The Bluetooth 5.0 Digital Amplifier Module can be used as a speaker that connects to a Raspberry Pi or mobile phone via Bluetooth. It has a volume control function and can be easily matched to high-powered speakers ranging from 40 watts to 200 watts. You then get two-channel stereo sound effects. A special firewall located on the board eliminates connection errors, including protection against reverse connection of the power supply and protection against short circuits. The module has the possibility of remote control within a radius of 15 meters from the device.

Instructions for connecting the module
When the power is connected, the blue indicator will flash. This indicates that the module is entering Bluetooth mode. It plays a beep and starts pairing devices. You now need to enable Bluetooth connectivity on your phone or Raspberry Pi. The name of the Bluetooth module you need to connect to is "XY-P40W". Another beep indicates that the pairing was successful.
Additional notes
1) Keep the repeater module as far away from the WiFi router as possible.
2. the voltage range should be between 5 V and 24 V DC. Exceeding 26 V will burn out the chip. 3.
3. the input voltage should not exceed:
- 16 V when connected with 4 Ω speakers
- 24 V when connected to 8 ohm speakers. 4.
4) The power supply current should not be less than 2 A.
When the supply voltage is low and the output power is relatively high, there is a risk of noise. The volume should then be reduced or the value of the supply voltage should be increased.
