Product details
Description
The DSD TECH HC-05 Classic Bluetooth 2.0 Serial Wireless Transceiver Module is a high-performance, 2-in-1 master and slave device engineered to integrate seamlessly into your electronic DIY projects. Designed for student innovators, hobbyists, and professional makers across India, this module serves as an efficient wireless replacement for traditional wired serial cables.
It allows your microcontrollers to communicate flawlessly with Android devices and personal computers. Operating on a versatile voltage range from 3.6 Volts to 6 Volts, it features a factory default baud rate of 9600 and a standard pairing PIN code of 1234.
The module comes built onto a robust 6-pin baseboard, completely shielded inside a clear, transparent protective case that prevents accidental short circuits and physical damage during breadboard testing. With its onboard tactile push button, entering AT command mode to customize your baud rates, device names, or roles is straightforward and seamless.
Whether you are building an automated robotic system, a remote-controlled lighting grid, or an interactive smart sensor network, this authentic imported communication module provides the stability and transmission range your custom builds require.
How to use
- Connect the VCC pin to 5 Volts and GND pin to the ground terminal on your microcontroller.
- Link the TXD pin of the module to your microcontroller Receiver and the RXD pin to the Transmitter using a proper voltage divider for safety.
- Power your development board, then pair it using an Android phone or computer by entering the default PIN code 1234.
- To modify settings via AT commands, hold down the onboard tactile button while supplying power to drop the system into configuration state.

FAQs
What is the use of HC-05 Bluetooth module?
The HC-05 Bluetooth module is designed to establish wireless serial communication between microcontrollers and external electronic devices. It acts as a transparent wireless bridge, enabling your project to receive data from or send commands to Android smartphones, laptops, and tablets without relying on physical wires.
How to use HC-05 Bluetooth module with Arduino Nano?
To use it with an Arduino Nano, map the module VCC and GND to the Nano power pins. Connect the module data lines to either the hardware serial pins or soft-serial pins on the Nano, keeping in mind that a logic level converter should be placed on the Nano 5 Volt transmission line to safely match the module 3.3 Volt logic level.
What is the range of an HC-05 Bluetooth module?
This module operates as a Class 2 Bluetooth device, providing a wireless coverage range of up to 10 meters in open, unobstructed environments. This coverage span makes it highly suited for home automation tasks, localized robotics, and classroom engineering experiments.
Are the DSD TECH modules sold on Dropy India authentic imports?
Yes, all DSD TECH microcontrollers and breakout boards available on our platform are 100 percent authentic items sourced directly from the United States. Dropy India handles the import process to deliver genuine, high-quality international components straight to your doorstep.
Does this wireless transceiver module support Apple iOS platforms?
No, this is a classic Bluetooth 2.0 Serial Port Profile module, which is natively incompatible with iPhone or iPad systems. If your current developmental setup demands seamless iOS control, you will need to choose a modern Bluetooth 4.0 Low Energy module instead.
