28+ Arduino Due Spi Pinout
Photos. Twi interface(sda, scl) x 2 (20,21),(70,71). Spi interface(mosi, miso, sck ,reset) x 1.

Before start programming for spi communication between two arduinos. Spi — serial peripheral interface. Arduino due board runs at 3.3, so i need to use a logic level converter because the rf24 pins are using 5v except for vcc(3.3v).
Read more about board specific functionality in the arduino due module documentation in the library reference.
The pins used to connect sd card module on the due are: Spi interface(mosi, miso, sck ,reset) x 1. Runs on an arduino due spi communication transaction list of commands. I connect the miso/mosi/sck to the icsp headers on the board and connect csn to pin 10, and ce to pin 9.
