- 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. |
