HC-05 is a classic master-slave integrated Bluetooth serial transceiver module for short-range wireless data transfer. It supports transparent transmission, so you can send and receive serial data without handling complex Bluetooth protocols. You can set it as master to actively search and connect slave devices, or set it as slave to wait for incoming connections. Enter AT command mode to modify name, baud rate, PIN code and working role. It adopts TTL level UART interface, directly connects to MCU serial pins. Widely used for wireless remote control, sensor data upload, Bluetooth serial communication and electronic DIY projects.
