Hi ST Micro Team,

Can I connect ST25RU3993 Single Chip UHF RFID to ESP32 board & read/write the Tags? Do I have to use any library for this?

Please suggest.

Regards
Shashank

    Hello,

    yes you can use an ESP32 board to drive an ST25RU3993.
    The HW requirements to operate the ST25RU3993 Reader IC is at least an SPI interface and one GPIO pin to detect IRQs transmitted by the ST25RU3993.

    Please have a look at the following ST Community discussion on how to interface the ST25RU3993 from an HPEV board with another MCU board.
