This Bluetooth audio module features the most recent Bluetooth V4.0 and is based on the CSR8645. It is an inexpensive, high-efficiency stereo wireless audio transmission device with intelligence for transmitting audio data. This module makes it simple to stream music wirelessly. It is primarily intended for short-range audio transmission, and it may be connected to Bluetooth-enabled devices such as laptops, cell phones, PDAs, and other digital product-connected devices.

It has a total of 6 function keys which is POWER-EN, PLAY, VOL+, VOL-, PREV, NEXT.
The key function is introduced as follows:
  1. POWER-EN: the switch control module when the switch, the toggle switch, when the POWER-EN is connected toBAT, module startup; When POWER-EN disconnect BAT, module shutdown, usually used when battery power. Adopting the module electrically powered, only the 10K POWER-EN series resistor connected to BAT, can realize the module electrically powered, usually used in the external power supply.
  2. PLAY: Play/Pause (short press), with the hang-up (by a long, time slightly longer), repairing (long press).
  3. VOL+: Volume plus.
  4. VOL-: the volume Minus.
  5. PREV: To the Previous Track.
