Product overview
Description
The ST25RU3993-EVAL board is a RAIN® RFID (UHF) reader system based on the ST25RU3993 integrated reader IC. The objective of the ST25RU3993-EVAL board is to provide engineers, students and technically interested people with a comprehensive RAIN RFID reader system, which allows evaluation of the properties and the feature set of the ST25RU3993. For this purpose the architecture of the ST25RU3993-EVAL board combines a high RF power, long-range reader and a low RF power, short-range RAIN RFID reader. In addition the ST25RU3993-EVAL board has been fitted with numerous easy to access test points and measurement possibilities.
The ST25RU3993-EVAL is controlled by a graphical user interface (GUI) running on a host PC through a USB/UART bridge (it requires a driver installation). The GUI can be found on www.st.com.
The ST25RU3993-EVAL is powered through a USB3.0 port to correctly operate the high RF power long-range configuration of the reader. If a USB3.0 port is not available, a USB2.0 Y-cable or an external power supply can be used to enable the long-range capabilities of the reader. If neither is available only the low RF power short-range reader configuration is available.
The ST25RU3993-EVAL provides two SMB (male) antenna connectors, which can be controlled via the GUI. To enable scanning for RAIN RFID transponders the user must connect the provided kit antenna or a suitable 50 Ω UHF antenna for the targeted frequency range.
The ST25RU3993-EVAL board supports frequency channels ranging from 840 to 960 MHz and Arm®-based devices.
