Raspberry Pi -  RFID Reader & Control Board

  

 

  

 

The RFID Reader  Board

1. provide 1 buzzer  (GPIO18)

2. provide 1 Big Push Switch (GPIO27)

3. provide RFID socket ( SPI signal) / NRF24L01 socket (SPI signal)

    you can choose use RFID or NRF24L01  ( both use SPI signal)

4. Provide 1 extra i2c device input port, for 5V device (with Logic Level converter)

5. provide DS18B20 temperature sensor socket (GPIO4)

6. provide IR Receiver sensor socket (GPIO23)

7. provide IR PIR motion sensor socket (GPIO22)

8. provide one Relay (GPIO17)

MF RC522 is applied to the highly integrated read and write
13.56MHz contactless communication card chip
Low-voltage, low-cost, small size of the non-contact card chip to read and write
Smart meters and portable handheld devices developed better choice
The MF RC522 use of advanced modulation and demodulation concept completely integrated in all types of 13.56MHz passive contactless communication methods and protocols
14443A compatible transponder signals
The digital part of to handle the ISO14443A frames and error detection.
support rapid CRYPTO1 encryption algorithm, terminology validation MIFARE products
MFRC522 support MIFARE series of high-speed non-contact communication, two-way data transmission rate up to 424kbit/s

  RFID reader & Relay  control

Support our Pi_Scratch software   Detail

Scratch control demo

1)Command "RFID"+"INIT"+"0" for ce0 
or "RFID"+"INIT"+"1" for ce1
will initial SPI signal to active RFID Reader
2) you will see "LastRFID" & "RFID" in Sensors
