The HC-05 6pin Bluetooth Module with Button is a popular and versatile module designed for adding Bluetooth wireless communication capabilities to your microcontroller-based projects. It communicates using the UART (Universal Asynchronous Receiver/Transmitter) protocol, making it easy to integrate with development platforms like Arduino, Raspberry Pi, ESP32, STM32, and others.
The HC-05 module stands out for its ability to operate in both master and slave modes, which means it can not only connect to Bluetooth-enabled devices like smartphones, tablets, or laptops (as a slave) but can also initiate communication with other slave devices (as a master). This is in contrast to the HC-06 module, which operates only in slave mode and cannot initiate connections. This added flexibility of the HC-05 makes it ideal for building wireless sensor networks, remote control systems, and inter-device Bluetooth communication.
The module features 6 pins: Key, VCC, GND, TXD, RXD, and State. The TXD and RXD pins are used to transmit and receive serial data, while VCC and GND provide the power supply. The Key pin is used to switch the module into AT command mode for configuration, and the State pin can indicate the connection status.
With a standard operating voltage of 3.3V to 5V and a range of up to 10 meters, the HC-05 is widely used in wireless robot control, Bluetooth data logging, home automation, wireless serial communication, and countless IoT projects. Its compact size, low power consumption, and ease of use make it a favorite among electronics hobbyists and students.
If you’re looking to build a Bluetooth-controlled robot, remote sensor system, or even a custom wireless communication interface, the HC-05 Bluetooth module is a reliable and cost-effective solution.
