HC-05 Bluetooth slave Module 3.3V HC05

HC-05 Bluetooth Slave Module 3.3V Product Description The HC-05 Bluetooth Slave Module is a compact Bluetooth Classic module designed for wireless serial communication between microcontrollers, computers, smartphones, and other Bluetooth-enabled devices. It uses the UART/TTL serial interface, making it easy to integrate with Arduino, ESP32-compatible projects, robotics, automation systems, and DIY electronics. The module can be configured using AT commands for parameters such as device name, baud rate, pairing settings, and operating mode. Typical HC-05 breakout boards provide VCC, GND, TXD, RXD, KEY/EN, and STATE connections. Features Bluetooth Classic 2.0 + EDR Easy UART serial communication Designed for slave-mode Bluetooth applications Compatible with Arduino and other microcontroller platforms Supports AT commands for configuration Built-in status LED Compact and easy to install Wireless communication range of approximately 10 meters in open conditions Suitable for replacing wired serial connections with wireless communication Applications Arduino Bluetooth Projects Bluetooth Robot Cars Wireless Robot Control Home Automation Industrial Automation Wireless Sensor Monitoring Serial Data Transfer Smartphone-Controlled Projects PC-to-Microcontroller Communication DIY Electronics Projects Package Includes 1 × HC-05 Bluetooth Slave Module Important Note The HC-05 uses 3.3V logic levels. When connecting the module's RX input to a 5V microcontroller, use an appropriate logic-level converter or voltage divider unless your particular breakout board explicitly provides 5V-level protection.
