Description

Based on the CSR BC4 chipset, the HC-06 supports Bluetooth V2.0 + EDR and operates as a slave device, allowing it to pair with Bluetooth masters such as computers, smartphones, tablets, and other controllers.

The module includes a built-in 3.3V voltage regulator and provides access to essential pins, making it safe and convenient to interface with 5V and 3.3V logic systems. Configuration such as device name, baud rate, and pairing password can be adjusted using AT commands when the module is not connected.

Once paired, communication works just like a standard UART serial connection, enabling reliable wireless data transfer.
