Comes with 3 Days Replacement Warranty. Click here to check our warranty policy.
This version of the popular Bluetooth uses the HC-05 module. This works 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. You can directly connect it to a 3.3V/5V microcontroller. You'll need a usb to serial converter to connect it to a computer.
By default, this bluetooth module is set to be on SLAVE mode. But you can reconfigure it with proper AT commands to use it as a MASTER device.

Q: When wiil be available? Questioned by Akmal101, 07-Jun-2015
Q: The actual hardware and mentioned specification was not the same. According to the spec, there should be a pin named "KEY" but in my case it was "EN". So I could not bring it to AT command mode. After searching the net, I found that there are some different versions of HC-05. Some of them have a push button. In my hardware, there was a space for push button but no push button were soldered there. I therefore shorted the push button terminal during the power up and able to enter into AT command mode. I think it should be mentioned clearly. Questioned by sadikhan, 07-Jun-2015

Q: connected the TXD to RX1 and RXD to TX1 of my leonardo. However the micro controller does not respond nor does it communicates with the HC 05. It connects to my phone successfully. Tried 4 to 5 different code but still doesnt work. Questioned by Ishat_Raihan, 14-Feb-2017
Please pair the device to your mobile with proper password and try with another arduino board. If you still think that the module is problematic, please send it back to us with a copy of your invoice. We will check that to give you a proper solution. Please note that warranty is applicable only if you complain within 7 days of purchase. Answered by A.R, 14-Feb-2017 17:40 PM
unfortunately I bought this about a month ago but didnt use it till today. I dont have another ardunio board so cant test it that way. The RX1 and TX1 leds do not flash either when connected to the HC-05. Can you give me any other tips about how can i fix this? Answered by Ishat_Raihan, 14-Feb-2017 17:52 PM

Q: And how do I connect a speaker's + and - to the module? Questioned by cyanpile65, 27-Aug-2017
Why should anyone do that? This one should be connected to arduino/ microcontroller by Tx and Rx pins. And the arduino/micrcontroller should drive the speaker. The VCC and GND pins of this module must be shorted with those of arduino/microcontroller. That's it. Answered by A.R, 27-Aug-2017 12:35 PM
