    Description

    The HC-05 Bluetooth module is a versatile and user-friendly wireless communication device designed for seamless integration with microcontrollers and embedded systems. It supports Bluetooth 2.0+EDR (Enhanced Data Rate) and provides reliable and efficient wireless data transmission. The module is commonly used in wireless control and data exchange applications, including home automation, robotics, and wireless sensor networks.

    Key Features:

    • Supports Bluetooth 2.0+EDR
    • Easy to integrate with microcontrollers via UART interface
    • Supports master and slave modes
    • Built-in antenna for reliable wireless communication
    • Configurable via AT commands
    • LED indicators for connection status
    • Low power consumption

    Technical Specifications:

    • Bluetooth Version: 2.0+EDR
    • Frequency Range: 2.4GHz ISM band
    • Operating Voltage: 3.3V to 5V
    • Communication Protocol: UART (default baud rate: 9600 bps)
    • Range: Up to 10 meters (unobstructed)
    • Power Consumption: 30mA in active mode, 8mA in idle mode
    • Dimensions: 37mm x 15mm x 3mm (varies slightly by manufacturer)
    • Operating Temperature Range: -20°C to +75°C

    Applications:

    • Wireless control of devices
    • Data exchange between microcontrollers and smartphones
    • Home automation systems
    • Robotics and RC projects
    • Wireless sensor networks
    • Prototyping and educational projects

    Usage:

    1. Connect the HC-05 module to your microcontroller or development board using the UART interface (TX, RX, VCC, and GND pins).
    2. Power the module with a voltage within the specified range (3.3V to 5V).
    3. Use AT commands to configure the module’s settings, such as baud rate, mode (master/slave), and pairing details.
    4. Pair the HC-05 module with another Bluetooth-enabled device (e.g., smartphone, PC) to establish a wireless connection.
    5. Exchange data between the paired devices via the UART interface.

    Caution:

    • Ensure the power supply voltage is within the specified range to avoid damaging the module.
    • Handle the module carefully to avoid physical damage to the components and antenna.
    • Verify the UART connections to ensure proper communication between the module and the microcontroller.
