JDY-31 SPP-C Bluetooth Module

The JDY-31 SPP-C module is a Bluetooth serial pass-through module based on the Bluetooth 2.0 protocol. It's commonly used in electronics projects that require Bluetooth communication between devices. The module allows for wireless serial communication between devices, enabling data transmission over Bluetooth. It typically operates in transparent mode, meaning it passes data between devices without interpreting or modifying it. It's important to note that the JDY-31 module uses an older Bluetooth version (2.0), which might have limitations compared to newer versions in terms of data transfer speed, range, and compatibility with newer Bluetooth-enabled devices. There might be newer versions or alternatives available if you're looking for more advanced Bluetooth functionalities. Note: The actual product may vary in slight variation in color and components with the image shown depending upon quantity availability.
