Datasheet

Either way, SPI is there for you. Connect Vin to 5V and GND to ground, then tie a wire from

AD to ground as well. Now connect the SCK, MISO, MOSI, CS and RST pins to your

microcontroller. If using an Arduino you can use either the hardware SPI pins which are fixed

for each Arduino, or go with software SPI where you select any 5 digital I/O pins
