.. [1] Configurable, typically defined as RST_PIN in sketch/program.
.. [2] Configurable, typically defined as SS_PIN in sketch/program.
.. [3] The SDA pin might be labeled SS on some/older MFRC522 boards.

Important: If your micro controller supports multiple SPI interfaces, the library only uses the **default (first) SPI** of the Arduino framework.
