In this projects we are going to use XS3868 Bluetooth module to convert our wired headphones to wireless one. XS3868 is based on OVC3860 RF transceiver. OCV3860 is low voltage single chip Bluetooth RF transceiver providing Bluetooth stereo solution. OVC3860 is a 2.4GHz transceiver with Bluetooth V2 baseband and can transfer 20bit high quality audio codec. OVC3860 is fetured with inbuilt power management and support advance lithium ion batteries with switch regulator.
This device can be program through serial port using AT commands, we will see this chapter later on how to program XS3868 using serial adapter.




Required Components:

  1. XS-3868 Bluetooth module.
  2. Good quality Headphones (wired).
  3. 10k resistor.
  4. 47uF capacitor.
  5. 3mm LED.
  6. 3.7v  Lithium ion battery.

Tools:

  1. Soldering ion
  2. Soldering paste
  3. Soldering tin wire
