Scope of Application
Long-range identification systems are becoming increasingly ubiquitous across various industries. The JRD-100, in particular, is a versatile system that has been adopted for a wide range of applications. For instance, the system is particularly well-suited for managing warehouse logistics, where it can be used to keep track of inventory and ensure that everything is in its proper place. This, in turn, helps to optimize supply chain management and ensure that products are delivered to customers in a timely and efficient manner.
Moreover, the JRD-100 has also found use in the automated retail trade, where it can be used to track inventory levels and ensure that there is always an adequate supply of products on hand. This is essential for ensuring that customers are always able to find what they need and that the business runs smoothly.
Finally, the JRD-100 is also an ideal solution for accounting and security systems. It can be used to keep track of financial transactions, monitor access to restricted areas, and ensure that only authorized personnel are able to enter certain areas. By using the JRD-100, companies can ensure that their assets are protected, their operations are running smoothly, and their employees are safe and secure.

The JRD-100 “Plug & Play” is connected via UART interface. Connect the EN pin to 5V and also install a pair of capacitors for power. Data transmission is controlled using a set of AT commands. The schematic of the JRD-100 module is shown below:
While the JRD-100 is an excellent solution for reading radio tags, it does have some limitations. For example, it has a limited reading distance of 1-2.5 meters, which may not be suitable for all applications. Additionally, the JRD-100 requires a specific voltage range of 3.3V to 5V, so it may not be compatible with all systems.
Another limitation of the JRD-100 is the lack of available manuals and example codes in the public domain. This can make it difficult for users to integrate the module into their systems and customize it to their specific needs.
Despite its limitations, the JRD-100 is still a reliable and efficient solution for applications that require long-range identification systems. By carefully considering its specifications and limitations, users can determine if the JRD-100 is the right choice for their specific needs.
The JRD-100 is a wireless ultra-high frequency (UHF) RFID tag reader that is widely used in a variety of fields. It has a high reading capacity, excellent accuracy, and sensitivity, making it an ideal choice for managing warehouse logistics, automated retail trade, and any accounting and security systems.
While the JRD-100 does have some limitations, such as its limited reading distance and specific voltage range, it remains a reliable and efficient solution for applications that require long-range identification systems. By carefully considering its specifications and limitations, users can determine if the JRD-100 is the right choice for their specific needs.
There are no manuals and examples of module integration in the public domain, so we ourselves developed the integration of UHF-RFID JRD-100 with Arduino. We’ll use STM32F103C8T6, you can use any compatible Arduino with two Hardware Serials or switch to Software Serial using Arduino Uno.
