HM-11 Bluetooth Module

It is a low power consumption SMD Bluetooth module using the TI CC2541 chip. The module allows you to quickly and easily set up BLE communications using the AT command with the manufacturer's pre-programmed firmware. Supports BLE communication with iPhone, iPad and Android 4.3. 

Supports AT command. Users can set the operating mode (master/slave), baud rate, device name, password password, etc.  

It is very suitable for your projects that require ultra-low power consumption.
