2 years ago I am using an esp-12E with the PN5180 reader. I modified the sample code to change the pinouts to the corresponding esp-12E versions
// ESP-12E <--> PN5180 pin mapping:
// 3.3V <--> 3.3V
// GND <--> GND
// SCLK, 14 --> SCLK
// MISO, 10 <-- MISO
// MOSI, 13 --> MOSI
// SS, 19 --> NSS (=Not SS -> active LOW)
// BUSY, 9 <-- BUSY
// Reset, 20 --> RST#elif defined(ARDUINO_ARCH_ESP8266)
#define PN5180_NSS 19
#define PN5180_BUSY 9
#define PN5180_RST 20It loads to ESP-12E but I see hard reset error repeats continuously:

Hi I'm testing the PN5180, and I connected the sensor and level converter to the Uno board.
There is only one PN5180 Hard-Reset..... in the console
I connected the wire with the same color as the circuit diagram.
