Abiding by the strict industrial norms and quality standards, we are engaged in supplying and trading Bluetooth Module. Our experts have designed and developed these modules by making use of latest technology as per the prevailing requirements of the industry. These blue tooth modules offers an option of slave and master mode to the user and are available in variety of specifications at most reasonable prices.

Our range comprises of the following products :

HC-06 Bluetooth Transceiver TTL


HC-06 Bluetooth Transceiver TTL

This is a bluetooth module for use with any microcontroller. It uses the UART protocol to make it easy to send and receive data wirelessly. The HC-06 module is a slave only device. This means that it can connect to most phones and computers with bluetooth but it cannot connect to other slave only devices such as keyboards and other HC-06 modules. To connect with other slave devices a master module would be necessary such as the HC-05 version which can do both master and slave.
  • A breakout board for easier connectivity
  • Designed for 3.3v level ttl but will accept 5v level as well
  • Built in antenna with a range of up to 30 feet (range is dependent on a lot of things such as any obstacles or walls in the way so it may vary)
  • Supports baud rates from 1200 to 1382400 bps (default is 9600 bps)
  • VCC input voltage 3.3v to 6v
  • Bluetooth Specification v2.0+EDR

HC-05 Bluetooth Transceiver TTL

The Bluetooth Module Breakout is the latest Bluetooth wireless serial cable! This version of the popular Bluetooth uses the HC-05/HC-06 module. 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. Do not attach this device directly to a serial port. You will need an RS232 to TTL converter circuit or Arduio XBee USB Adapter if you need to attach this to a computer. You can either solder a 6-pin header or individual wires.


Unit comes without a connector. Please see related male and female pins below.


And now, we provide HC-05/06, HC-05 could be setting to Master or Slave by user. HC-06 just be Master or Slave, that could be customized. This module default is HC-06 with Slave mode.

Bluetooth Module HC 06

These small size Bluetooth TTL transceiver modules are designed for serial communication (SPP - serial port profile). It allows your target device to both send or receive TTL data via Bluetooth technology without connecting a serial cable to your computer.

The modules with the HC-06 firmware are the modules which are factory set to be Master or Slave modules. Master and slave mode cannot be switched from the factory setting. HC-06 is a commercial grade product.
