PN5180 NFC reader (13.56 MHz, ISO 15693) con ESP32

Alimentazione 3.3-5 V Bus SPI

Pin e collegamento all’ESP32

Pin	Ruolo	Pin ESP32	Note
5V	Non collegato all’ESP32	—	RF supply: connect to VIN (5 V). The reader needs both 5 V and 3.3 V
3.3V	Alimentazione	3V3	Logic supply: connect to 3V3
RST	Ingresso (lo pilota l’ESP32)	D25	Reset, active LOW
NSS	Chip select SPI	D5	SPI chip select
MOSI	SPI MOSI	D23
MISO	SPI MISO	D19
SCK	Clock SPI	D18
BUSY	Uscita (la pilota il componente)	D26	HIGH while the chip is busy. Wait for LOW before each SPI command
GND	Massa	GND
GPIO	Non collegato all’ESP32	—	Not needed
IRQ	Interrupt	D35	Interrupt, optional
AUX	Non collegato all’ESP32	—	Test output, not needed
REQ	Non collegato all’ESP32	—	Firmware download only. Leave unconnected

Collegamento consigliato per l’ESP32 DevKit a 30 pin, evitando i pin della flash, di sola lettura e di strapping. BoardPilot lo controlla mentre colleghi.
