STMicroelectronics' ST25RU3993-EVAL board is a RAIN RFID (UHF) reader system based on the ST25RU3993 integrated reader IC. The board provides a comprehensive reader system allowing the evaluation of the ST25RU3993 reader's feature-set and properties. For this purpose, the architecture of the ST25RU3993-EVAL board combines a high RF power, a long-range reader, and a low RF power short-ranged RAIN RFID reader. The ST25RU3993-EVAL board is fitted with numerous easy-to-access test points and measurement possibilities.
