The HC-06 Bluetooth module is a compact, easy-to-use serial Bluetooth transceiver that supports slave-only functionality. It enables wireless serial communication between microcontrollers (like Arduino, STM32, or Raspberry Pi) and Bluetooth-enabled devices such as smartphones, tablets, or computers.
Designed to provide transparent serial communication over Bluetooth, the HC-06 converts serial TTL signals to Bluetooth SPP (Serial Port Profile), enabling cable-free data transfer in embedded projects. It is ideal for short-range wireless control, sensor logging, and DIY automation applications.
Bluetooth Version: 2.0 SPP (Slave Only) Interface: TTL Serial (3.3V logic) Baud Rate: Default 9600 bps, configurable Range: ~10 meters Features: Plug-and-play for Arduino, Raspberry Pi Compact, low-cost Requires no AT mode switching (slave-only) Applications: Serial wireless communication, robot control, DIY electronics
