Host interface and GPIO connection
The
X-NUCLEO-NFC08A1
expansion board contains the ST25R3916-AQFT chip and is powered by the
STM32
Nucleo
board.
The
ST25R3916B
is driven by the microcontroller via SPI interface.
The six LEDs indicate the detected RFID technology (for example, ISO14443 Type A for LED4).
