HKD Original HC-06 Bluetooth Module | Wireless Serial Transceiver 3.6-6V

The HKD Original HC-06 Bluetooth Transceiver Module is a compact and reliable wireless communication module designed for Arduino, microcontrollers, and embedded systems. Operating as a slave device, it provides a simple interface for serial communication via VCC, GND, TXD, RXD, and an optional LED status pin.

The built-in LED indicator allows easy monitoring of Bluetooth status: flashing indicates no connection, while a steady light shows an active Bluetooth connection with an open port. The module features a 3.3V LDO voltage regulator, supporting an input voltage range of 3.6-6V (do not exceed 7V) and drawing about 30mA when unpaired and 10mA when paired, making it energy-efficient for battery-powered projects.

With 3.3V logic level compatibility, it can connect directly to popular microcontrollers such as 51, AVR, PIC, ARM, MSP430, and even 5V microcontrollers without the need for a level shifter like MAX232. The HC-06 module is ideal for wireless serial communication, IoT devices, robotics, smart home systems, and DIY electronics.
