Product Short Description

The HC-05 6-Pin Bluetooth Wireless Serial Transceiver Module is a highly versatile wireless data link designed for effortless microcontroller communication. Featuring integrated master-and-slave operational capabilities, this board easily converts standard wired UART/RS232 serial pipelines into stable, long-range Bluetooth connections. The module comes mounted on a 6-pin breakout board equipped with an on-board 3.3V voltage regulator, an integrated pairing status LED indicator, and a physical hardware reset/clear toggle button. Fully compatible with Arduino, Raspberry Pi, and industrial MCU setups, it provides the ultimate plug-and-play solution for configuring wireless robotics control, remote sensor data collection arrays, and seamless smart-home telemetry systems.

Product Description

Bridge the gap between your physical hardware and wireless devices with the HC-05 6-Pin Bluetooth Wireless Serial Transceiver Module. This widely acclaimed, high-performance communication board acts as a wireless transparent data pipe, allowing your microcontrollers to communicate seamlessly with smartphones, tablets, laptops, and other Bluetooth-enabled devices. It is an indispensable networking component for robotics developers, IoT engineers, and hardware hobbyists seeking to cut the cords on their electronic setups.

Unlike basic slave-only modules, the versatile HC-05 can be configured as either a Master or a Slave node using simple, standard AT command sets. This allows two separate microcontroller setups to discover and pair with each other automatically across mid-range open distances. The core chip is expertly mounted on a robust 6-pin breakout host board that takes care of complex power logistics. It features an onboard 3.3V low-dropout voltage regulator, enabling the module to accept standard 5V power rails from an Arduino safely while preserving low-power consumption metrics.

Designed for quick deployment and debugging, the module is equipped with a high-visibility onboard status LED that changes its flash frequency to indicate whether the board is searching for a connection, enter-programming mode, or successfully paired. A built-in physical micro-tactile push button gives you instant hardware access to clear pairing data or enter command mode instantly. Outfitted with right-angle header pins for clean horizontal integration into tightly packed chassis and custom sensor arrays, this Bluetooth transceiver is the ultimate module for automated weather stations, wireless remote-controlled vehicles, smart home automation, and real-time serial telemetry tracking.

Key Features

Master & Slave Dual Modality: Easily toggle the module via software commands to act as a data broadcaster (Master) or receiver (Slave).
Transparent UART Serial Pass-Through: Treats wireless communication exactly like a traditional wired serial connection, removing the need for complex custom drivers.
Onboard Voltage Regulation: Features a robust power chip that accepts a wide 3.6V to 6V input voltage while providing a safe 3.3V operational environment.
Hardware Reset Button: Outfitted with an onboard micro-switch for quick, solderless access to entering programming state or clearing saved connections.
Visual Status LED Indicator: High-brightness light flashes dynamically to communicate pairing statuses, search windows, and transmission states at a glance.
Industrial Standard Pinout: Fully broken out into standard 6 pins (VCC, GND, TXD, RXD, STATE, EN) for streamlined integration with microcontrollers.
