Product details

Description

The DSD TECH HC-05 Bluetooth Serial Pass-through Module is a premium, high-performance wireless communication solution engineered for electronics hobbyists, students, and developers. This classic Bluetooth 2.0 transceiver serves as a wireless replacement for traditional wired serial cables, allowing seamless data transmission between microcontrollers and external devices like Android smartphones, laptops, or desktop computers. Powered by the reliable CSR BC417 mainstream chipset, it complies fully with standard Serial Port Profile protocol regulations for stable and continuous data flow.

Designed specifically for versatile prototyping, this board functions as a flexible two-in-one module that easily switches between master and slave configurations through simple AT commands. It operates across a broad working voltage range from 3.6 Volts to 6 Volts, making it highly compatible with standard five Volt systems. An integrated physical push button provides direct, hassle-free toggling into command mode, eliminating complex wiring workarounds during initial configuration setup.

Whether you are constructing autonomous robotic rovers, smart home automation hubs, or remote data telemetry systems, this module provides an efficient way to add wireless functionality to your projects. The unit comes equipped with a convenient clear protective plastic cover that safeguards delicate onboard circuitry against accidental shorts and physical damage during handling or deployment.

How to use

  1. Connect the power pin to a five Volt power supply and ground pin to ground on your microcontroller board.
  2. Wire the transmitter pin of the module to the receiver pin of the microcontroller, and the receiver pin of the module to the transmitter pin of the microcontroller.
  3. Press and hold the physical button while powering up the circuit to enter AT command configuration mode.
  4. Pair the module with your Android or Windows device using the default passcode 1234 at a default baud rate of 9600.

FAQs

What is the difference between HC-05 and HC-06?

The primary difference lies in operational flexibility. The HC-05 module can function as both a master and a slave device, enabling it to initiate or accept connections, whereas the HC-06 module is strictly limited to operating in slave mode.

How does the HC-05 Bluetooth module work?

It works as a wireless serial pass-through interface utilizing the Serial Port Profile standard. Data received wirelessly from a paired device is transmitted out through the physical transmitter pin, and any data fed into the receiver pin is transmitted back wirelessly.

What is the range of an HC-05 Bluetooth module?

This classic Bluetooth module typically offers a reliable indoor operating range of approximately 10 meters. This distance can extend up to 30 meters in open outdoor environments without physical obstructions or signal interference.

Is this authentic DSD TECH module available in India?

Yes, Dropy India directly sources and imports authentic DSD TECH products from the United States of America. Every module is guaranteed genuine, allowing Indian makers and developers to build their electronics projects with high-quality global components.

Can HC-05 communicate with smartphones?

The module can easily communicate with Android smartphones and Windows devices using standard Bluetooth terminal applications. However, please note that it uses classic Bluetooth 2.0 technology and is not compatible with Apple iOS devices like iPhones or iPads.
