HC-05 Bluetooth Module is an easy to use Bluetooth SPP (Serial Port Protocol) module, designed for transparent wireless serial connection setup. Its communication is via serial communication which makes an easy way to interface with controller or PC. HC-05 Bluetooth module provides switching mode between master and slave mode which means it able to use neither receiving nor transmitting data.

input power supply 3.3~6V, Prohibit more than 7V No “Automatically prevent power supply peversing func”, so please correctly connect power supply.
We advise to install “Bluetooth master module”
The “State” is output foot for LED status, when bluetooth “Unconnected”, output “Pulse” ; when bluetooth “connected”, output “High level”, we can determine the states from “MCU”
If only the board , No any “Bluetooth Function ”
