Product Name: HC-06 Bluetooth Module Original
The HC-06 Bluetooth module is a cost-effective, compact solution for short-range wireless serial communication. Designed to function in **slave mode only**, it allows devices like Arduino, ESP32, and Raspberry Pi to communicate wirelessly over Bluetooth V2.0. With a simple UART interface and onboard voltage regulator, it's an ideal choice for remote control systems, wireless data logging, and IoT projects.

How to Use:
Connect the HC-06 module to any microcontroller (e.g., Arduino) using UART. Connect TX of HC-06 to RX of Arduino and RX of HC-06 to TX of Arduino via a voltage divider (to drop 5V to 3.3V). Set the serial baud rate to 9600 in your code. The default pairing password is
1234. Use any Bluetooth terminal app or another master module to pair and exchange data wirelessly.
Using Purposes:
- Wireless control of Arduino-based robots or devices
- Remote monitoring of sensors
- Serial communication with Android/PC via Bluetooth
- DIY IoT projects requiring Bluetooth slave modules
