JDY-31 Pin Functions
PIN | Pin Function |
VCC | Power supply pin is connected to the positive power supply (recommend 5V). By providing the module with an appropriate power supply, it can operate normally. |
GND | The ground pin is connected to the negative ground terminal. It is used to form a circuit loop with the power supply pin to provide the grounding for the power supply. |
TXD | Serial data transmission pin, used to send data from the module to an external device. You can connect the receiving pin (RXD) of the external device to the TXD pin of JDY-31 to receive data from the Bluetooth module. |
RXD | Serial data receiving pin, used to receive data sent by external devices. You can connect the transmitting pin (TXD) of the external device to the RXD pin of JDY-31 to send data to the Bluetooth module. |
EN | The enable pin is used to control the working state of the module. By providing a high level (usually 3.3V or 5V) to the EN pin, the module can be put into operation. When there is no input to the enable pin or a low level is given, the module will be in a low-power standby state. |
STATE | The status pin is used to provide the status information of the module. By monitoring the level changes of the STATE pin, you can obtain the connection status of the module or other related status information. |
JDY-31 Note
- Connection issue: If the module fails to connect, check whether it is in the correct working mode and ensure that the main device can detect the JDY-31 module.
- Compatibility issue: In different computer systems, some USB-to-TTL modules may have compatibility problems. It is recommended to use the CH340 module for testing.
By following the above precautions, you can use the JDY-31 Bluetooth module for wireless communication more smoothly. Make sure to carefully read the relevant documentation before use, so as to better understand the functions and limitations of the module.
JDY-31 Application
With the development of Internet of Things technology, the application scenarios of Bluetooth modules are becoming increasingly widespread. JDY-31, with its excellent performance and compatibility, has great potential for development in multiple fields such as smart home, remote monitoring, and wearable devices.
In the future, we can expect JDY-31 to further optimize its software protocol stack, enhance compatibility with more devices, and even possibly introduce more intelligent features, such as automatic pairing and adaptive transmission rate adjustment, to provide users with a more convenient and efficient usage experience.
In conclusion, the JDY-31 baseboard Bluetooth module is not only a high-performance hardware product, but also one of the key technologies driving the development of smart devices. Whether you are an electronics enthusiast or a professional developer, you should consider this powerful tool. It might become the secret weapon for your next innovative project.
