+| MFRC522 RFID Reader | ESP32 | Description |
+|---------------------|-------|-------------|
+| SDA | GPIO 5 | SPI signal input, I2C data line, or UART data input |
+| SCK | GPIO 18 | SPI clock |
+| MOSI | GPIO 23 | SPI data input |
+| MISO | GPIO 19 | SPI master-in-slave-out, I2C serial clock, or UART serial output |
+| IRQ | Don't connect | Interrupt pin; signals the microcontroller when an RFID tag is nearby |
+| GND | GND | Ground connection |
+| RST | GPIO 21 | LOW signal to put the module in power-down mode; send a HIGH signal to reset the module |
+| 3.3V | 3.3V | Power supply (2.5-3.3V) |
