Description

This nifty Bluetooth module does one thing, but it does it well: give it some power and it will drive 2 small speakers. Perfect for a DIY portable speaker system. When powered up, you should see a Bluetooth device called “DW-CT14+” – connect to that, then play some audio!

Bluetooth version: the bluetooth version is 4.2. It can be compatible with all mobile phone and bluetooth adapters on the market. The distance is about 15 meters. Supports automatic return of paired devices and automatically broadcasts music. 

You can also power this with a lithium polymer battery to make it completely portable!

Pigtails included!
