The RC522 module works on 13. The module allows the developers to interface it with any other SPI, I2C, and UART based microcontrollers. The RC522 is known as MFRC-522 due to its NFX semiconductor microcontroller. USART in SPI Mode The Universal Synchronous and Asynchronous serial Receiver and Transmitter (USART) can be set to a master SPI compliant mode of operation. I dont know if there is a library for this. But the SPI library does include the support. With a 2560, you can also use the USART as SPI, so you can have 2 SPI ports. These pins support SPI communication, which, although provided by the underlying hardware, is not currently included in the Arduino language. Arduino Due pinout is explained in detail in this post. SPI: 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK). This board is powered by a 32-bit ARM cortex-M3 processor Atmel SAM3X8E. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. On the pinout diagrams it says 50, 51, 52 are on the block of connectors and the ICSP. La liaison SPI Arduino: exemple, description Caractéristiques Arduino MEGA 2560.

RC522 is a Multi-communication RFID Module for Arduino and Microcontrollers. It was launched by Arduino company in 2012. I have a couple of questions: If I use the ICSP header, does that directly link to pins 50 - 52.
