What is an M5 Stack RFID RC522 Panel and Specifications

A panel that is compatible with the FACES kit and has an embedded radio frequency identification chipset is called FACE-RFID.
It is MFRC522-based, just like RFID units. The MFRC522 communicates with the proximity RF card using the modulation and demodulation method while operating in the 13.56MHz frequency band.
This device can recognize and record information from many cards, encode and authorize an RF card, and perform the functions of a card reading and writing device. You can have an upgraded level of RFID gadget with a more thorough and contained pattern with a FACES panel.

Pin Configuration of M5 Stack RFID RC522 Panel

Here RC522 is an RFID module, pin configuration of the RFID RC522 panel pinout is given below.

Pin Number	Pin Name	Description
1	VCC	Used to supply power (3.3V) to the module.
2	RST	Used to reset or power down the module. Hard power-down would be activated when this pin goes low.
3	GND	Ground pin, connected to the GND system of Arduino
4	IRAQ	The interrupt pin is used to alter the MCU as soon as the RFID tag shows up in its section.
5	MISO/SCL/Tx	It functions as SCL for the I2C interface and Tx for the UART interface in SPI communication.
6	MOSI	The Master Out Slave In pin is set to input for SPI communication
7	SCK	It provides a clock source for the SPI bus Master (e.g. Arduino).
8	SS/SDA/Rx	It functions as SS (Serial input) during SPI communication, SDA for IIC, and Rx in UART.
