Its purpose is to provide a comprehensive RAIN RFID reader system that allows the user to evaluate the properties and the features of ST25RU3993. To achieve this goal the ST25RU3993-HPEV board, differently from a typical reference design approach, combines a high RF power and a low RF power RFID reader on a single PCB. Additionally, the ST25RU3993-HPEV board is outfitted with several easy-to-access test points and measurement possibilities. With minor modifications it is possible to change the architecture of the reader, for example, it is possible to control the RF circuitry with external MCU or vice versa. Bypassing the external on-board power amplifier or alternate antenna configurations are additional possibilities. The ST25RU3993-HPEV is controlled by a graphical user interface (GUI) running on a host PC. The corresponding interface is a USB / UART bridge (requires driver installation). The GUI can be found in dedicated pages on www.st.com. The board supports tuning the radio frequency from 840 to 960 MHz. and provides two SMB (male) antenna connectors that can be controlled via the GUI. To enable scanning for RAIN RFID transponders connect a suitable 50 UHF antenna for the targeted frequency range. 2/10 DB4247 Rev 4
