Description
The JDY-31B Bluetooth module provides a robust wireless serial bridge for IoT and embedded systems. Based on Bluetooth 3.0 Classic technology, it implements the Serial Port Profile (SPP) to create a transparent, two-way data channel between a microcontroller’s UART and any Bluetooth-enabled host, such as a smartphone or computer. The module is pre-soldered onto a breakout board, offering immediate access to power, ground, transmit, and receive pins for hassle-free integration.
Engineered for reliability, the module features strong anti-interference performance and stable connectivity for continuous data streaming. Its low-power design and support for configurable baud rates up to 128000 make it versatile for applications requiring varying data throughput. The JDY-31B serves as a direct, pin-compatible upgrade or replacement for popular HC-05/HC-06 modules, enabling seamless migration in existing projects with enhanced convenience from the included base plate.
