It also has 3 buttons for various commands.

     During lithium battery use, the battery can be charged over the micro usb connection. The wireless audio playback function continues during charging. Many devices do not support charging and audio playback at the same time. The red led shows the power status of the board / the status of the battery charging process. The yellow led shows the battery charge status.

• When only usb power is connected; the red led blinks. This shows the normal operating status.
• If only the battery is connected; the yellow led is on continuously. Blinking of the yellow led shows that the battery voltage has decreased.
• When the battery and microusb connection are made at the same time;  Blinking of the red led shows that the battery charging is continuing. Continuous lighting of the red shows that the battery is charged.

     Disconnecting the usb connection while the battery charging is continuing causes the device to restart. After a while the device will make the connection wirelessly again and continue to work. During this time the audio will be interrupted.

     When the product is used with a phone, voice conversation can be made with the microphone on the board. When a phone call occurs, voice conversation can be started by pressing the playstop button on the board.

     By soldering the pads on the back of the board it can be operated as a pc sound card. When the connection is established with a usb cable, computer sounds will start to be transferred out over the module.

     The mute setting next to the antenna is set to give sound. If the mute resistor is moved to the side, the sound goes to the off position.
