2. Default factory settings:
1. The red port is connected to a DC5V power supply (can be powered by a lithium battery), no more than 5.2V
2. The white port is connected to the speaker, 2*5W, can be connected to two 4 ohm or 2 ohm 3~5W speakers
3. The power-on is set to on by default, and there will be a prompt sound when it is turned on.
4. The default reminder sound is a neutral "beep"
5. The default Bluetooth device name is "Bluetooth"
6.Bluetooth version: v5.1+EDR
3. Wiring method
Red connector: power supply
This cannot be used for 3.3~5.0V DC power supply, 12V or 24V or higher voltage power supply scenarios, and other high voltage versions should be selected.
White connector*2: speaker
The two white interfaces can be connected to two 3~5W speakers respectively (they can also be used as mono, just use one speaker interface and leave the other empty). There is no requirement for the impedance of the speaker (2 ohms, 4 ohms, and 8 ohms are all acceptable).
