V5.0 XY-WRBT Bluetooth Decoder Audio Module
Description of the interface:
The power supply has multiple options for compatibility, such as a Micro-USB mobile phone charger, a 3.7-4.2V lithium battery, or a 3.7-24V DC power supply. Simply choose the most suitable one for your needs.
To activate the on/off function of the V5.0 XY-WRBT Bluetooth Decoder Audio Module board, simply short-circuit it for 2 seconds. V5.0 XY-WRBT Bluetooth Decoder Audio Module is especially useful for battery-powered situations, as turning off the board when not in use helps conserve power and allows for easy modifications.
Please make sure to follow the given directions carefully in order to avoid any errors.
After turning on the power, the blue indicator light will quickly flash and switch to Bluetooth mode. Upon hearing a “beep,” it will enter pairing mode and await connection. Look for “XY-WRBT” (the power amplifier board’s device name) in your phone’s Bluetooth settings and click to connect. A confirmation “beep” will sound when connected and the indicator light will remain on. You can now play music from your phone, with the light flashing slowly while music is playing. When disconnecting from Bluetooth, the power amplifier board is ready for its next pairing session, signaled by a “beep” and entering pairing mode once again.
When handling a 3.7V lithium battery, it is important to take proper precautions.
If the battery voltage falls below 3.3V while powering the decoder board, V5.0 XY-WRBT Bluetooth Decoder Audio Module will shut down automatically. Simply short-circuit the on/off contact for 2 seconds after re-powering or fully charging to restart it.
When relying on battery power, a “sizzling” noise may occur if the voltage is too low. In such a situation, recharging the battery is necessary.
To ensure safe usage, V5.0 XY-WRBT Bluetooth Decoder Audio Module is advised to utilize a lithium battery with a built-in protection board when utilizing the decoder board, as it lacks its own charging safeguard system.
You may use a Micro USB to directly charge your rechargeable battery if it supports this feature.
