Product Description
The HC-06 (Compatible Type-D) is a professional-grade Bluetooth 2.0+EDR (Enhanced Data Rate) slave module designed for stable, short-range wireless serial communication. As a dedicated Slave-only device, it is specifically engineered to be “discovered” and controlled by a Master device, such as an Android smartphone, tablet, or PC.
The Type-D Compatible version is a refined hardware revision known for its high resistance to signal interference and its “always-ready” pairing state. It functions as a transparent wireless bridge: once a connection is established, the module passes TTL serial data back and forth as if there were a physical cable between your hardware and the remote controller. With its streamlined 4-pin interface and integrated voltage regulation, it offers a “plug-and-play” experience for Arduino, Raspberry Pi, and Industrial PLC systems.
Key Features
- Dedicated Slave Operation: Optimized for peripheral use, ensuring rapid discovery and a stable, “locked” pairing state with master controllers.
- Transparent Data Transmission: No complex Bluetooth protocol knowledge is required; it functions exactly like a wireless RS232 cable for standard TTL serial communication.
- Type-D Industrial Stability: Features a hardware layout optimized for low-latency data throughput and reduced packet loss in electronically noisy environments.
- Wide Power Input: The onboard breakout board includes a 3.3V LDO regulator, allowing the module to be powered safely by any source between 3.6V and 6.0V DC.
- Low Operating Current: Optimized for active data transmission with a low power footprint, making it suitable for battery-powered IoT devices and handheld tools.
- Visual Status LED: Features a bright onboard LED: fast flashing indicates searching/pairing mode, while a steady light indicates a successful connection
