The HC-05 Bluetooth Module is a popular wireless serial communication module that enables Bluetooth connectivity between microcontrollers and smartphones, computers, or other Bluetooth-enabled devices. It supports easy UART communication and is widely used in robotics, IoT, and embedded system projects.
The HC-05 Bluetooth Module is based on the Bluetooth 2.0 + EDR standard and provides reliable wireless serial communication over a range of up to 10 meters. It can operate in both Master and Slave modes, allowing it to either connect to other Bluetooth devices or accept incoming connections.
The module communicates through a UART (TX/RX) interface, making it simple to integrate with Arduino, ESP32, STM32, Raspberry Pi, and other microcontrollers. It supports AT commands for configuration, enabling users to change the device name, baud rate, PIN code, and operating mode. The onboard voltage regulator allows the module to be powered from a 3.6V–6V supply, while the communication logic operates at 3.3V TTL levels.
