3.1 Host interface and GPIO connection
The X-NUCLEO-NFC06A1 expansion board contains the ST25R3916-AQFT chip and is powered by the STM32
Nucleo board.
The ST25R3916 is driven by the microcontroller via SPI interface.
The six LEDs indicate the detected RFID technology (for example, ISO14443 T
ype A for LED4).

3.3 ST25R3916 device
The ST25R3916 is a high performance NFC universal device supporting NFC initiator, NFC target, NFC reader,
and NFC card emulation modes.
The ST25R3916 includes an advanced analog front end (AFE) and a highly integrated data framing system for:
• ISO 18092 passive and active initiator, ISO18092 passive and active target
• NFC-A/B (ISO 14443A/B) reader including higher bit rates
