Product Description
The HC-05 (Non-Compatible Type-D) is a specialized version of the industry-standard Bluetooth 2.0+EDR serial pass-through module. While it maintains the core functionality of the HC-05—acting as a Master or Slave dual-role wireless bridge—the Type-D variant is distinguished by its unique firmware and hardware layout.
“Non-Compatible” refers to its specific command set and timing requirements, which may differ from generic Type-A or Type-B clones. This makes it an excellent choice for businesses and developers who require a consistent, specific hardware revision for proprietary systems. It features an onboard tactile button to manually trigger AT Command Mode, allowing for deep customization of the device name, pairing PIN, and baud rate. Mounted on a robust 6-pin breakout board with a 3.3V LDO regulator, it is designed for stable serial communication between microcontrollers, PCs, and Android devices.
Key Features
- Master/Slave Switchable: Fully configurable to either initiate connections (Master) or accept them (Slave), enabling peer-to-peer module communication.
- Onboard Configuration Button: A dedicated physical switch provides a reliable hardware method to enter “Command Mode” for internal settings adjustments.
- Type-D Specific Firmware: Offers a stable and consistent instruction set for specialized industrial applications where generic “compatible” modules may vary.
- Transparent Data Transfer: Functions as a wireless serial port; once paired, data is transmitted seamlessly without needing complex protocol handling.
- Wide Input Voltage: The integrated baseboard supports a 3.6V to 6V power range, making it compatible with standard 5V logic systems and battery packs.
- Visual Status LED: Onboard LED indicates searching (fast flash), AT mode (slow flash), and connected status (double-flash).
