Description

The HC-06 Bluetooth Module is a simple and cost-effective serial communication module designed for wireless data transfer.
It operates as a slave-only device, pairing with master Bluetooth devices to exchange data over UART (TX/RX).
The module supports a communication range of up to 10 meters and is commonly used in Arduino, ESP32, ESP8266, and Raspberry Pi projects for remote control, sensor data transmission, and serial communication replacement.

HC-06 is easy to integrate into projects, requiring only power, ground, TX, and RX connections. It is widely used in IoT, robotics, home automation, and educational electronics.
