| Pin | Function Description | Pin | Function Description |
| 3.3V | 3.3V power input pin | 5V | 5V power input pin |
| MISO | SPI master input slave output pin | GND | Power ground pin |
| MOSI | SPI master output slave input pin | RST | W5500 hardware initialization pin (active low) |
| SCS | SPI SLAVE select pin (active low) | INT | W5500 interrupt pin (active low) |
| SCLK | SPI clock pin | NC | Hanging |
Note 1: The operating voltage of the W5500 is 3.3V, but the I/O port can withstand 5V.
Note 2: The YIXIN_W5500 module has two power supply modes, namely 3.3V power supply or 5V power supply. When using 5V power supply, the “3.3V” pin will have a 3.3V voltage output.
