Product Description
The HC-06 (Compatible Type-B) is a highly reliable Bluetooth 2.0+EDR (Enhanced Data Rate) slave module designed for seamless, short-range wireless serial communication. Built as a “Slave-only” device, it is specifically engineered to be discovered and paired with by “Master” devices such as Android smartphones, tablets, or PCs.
The Type-B Compatible version offers an optimized hardware layout for maximum stability in diverse electronic environments. It functions as a “Transparent Wireless Bridge”—once connected, the module passes TTL serial data back and forth as if there were a physical cable between your hardware and the remote device. With its streamlined 4-pin interface (VCC, GND, TXD, RXD) and integrated voltage regulation, it is a “plug-and-play” favorite for adding wireless capabilities to Arduino, Raspberry Pi, and Industrial PLC systems.
Key Features
- Dedicated Slave Mode: Optimized as a “set-and-forget” peripheral, ensuring rapid discovery and stable pairing with master controllers.
- Transparent Serial Data: Requires no complex Bluetooth protocol handling; functions exactly like a wireless RS232 cable for standard TTL serial communication.
- 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.
- High-Speed Data Throughput: Features EDR (Enhanced Data Rate) to ensure low-latency data transmission, ideal for real-time sensor updates and motor control.
- Broad Compatibility: Specifically designed to work reliably across a wide range of platforms including Android, Windows, and Linux-based systems.
- Visual Status LED: Features a bright onboard LED: fast flashing indicates searching/pairing mode, while a steady light indicates a successful connection.
