HC-05 Bluetooth Module for Arduino

HC-05 Bluetooth Module In Pakistan TTL Module (With EN Pin) Breakout is the latest Bluetooth wireless serial Module. This version of the popular Bluetooth module uses the HC-05. These modems work as a serial (RX/TX) pipe. Any serial stream from 9600 to 115200bps can be passed seamlessly from your computer to your target. The remote unit can be powered from 3.3V up to 6V for easy battery attachment. All signal pins on the remote unit are 3V-6V tolerant. No level shifting is required.

Specifications:

Pin Configuration

Pin Number Pin Name Description

1 Enable / Key This pin is used to toggle between Data Mode (set low) and AT command mode (set high). By default it is in Data mode

2 Vcc Powers the module. Connect to +5V Supply voltage

3 Ground Ground pin of module, connect to system ground.

4 TX – Transmitter Transmits Serial Data. Everything received via Bluetooth will be given out by this pin as serial data.

5 RX – Receiver Receive Serial Data. Every serial data given to this pin will be broadcasted via Bluetooth

6 State The state pin is connected to on board LED, it can be used as a feedback to check if Bluetooth is working properly.

7 LED Indicates the status of Module

Blink once in 2 sec: Module has entered Command Mode

Repeated Blinking: Waiting for connection in Data Mode

Blink twice in 1 sec: Connection successful in Data Mode

8 Button Used to control the Key/Enable pin to toggle between Data and command Mode

Applications:

HC-05 is a Bluetooth module which is designed for wireless communication. This module can be used in a master or slave configuration.

It is used for many applications like wireless headset, game controllers, wireless mouse, wireless keyboard and many more consumer applications.

It has range up to <100m which depends upon transmitter and receiver, atmosphere, geographic & urban conditions.

It is IEEE 802.15.1 standardized protocol, through which one can build wireless Personal Area Network (PAN). It uses frequency-hopping spread spectrum (FHSS) radio technology to send data over air.

It uses serial communication to communicate with devices. It communicates with microcontroller using serial port (USART).
