The HC-05 Bluetooth Module is a versatile and widely used serial communication module.
Unlike the HC-06, it can operate as master or slave<\/strong>, making it suitable for both point-to-point and master-slave Bluetooth applications.<\/p>\n

It communicates via UART (TX\/RX)<\/strong> and is compatible with Arduino, ESP32, ESP8266, and Raspberry Pi<\/strong>, enabling wireless control, sensor data transmission, and remote debugging.
HC-05 is ideal for robotics, IoT, home automation, and wireless serial communication projects.<\/p>\n
