Is the pins, and I'm a little confused on how to connect this board via SPI.

  • VCC (Power supply) <-> 5V
  • RST (Reset) <-> 9
  • GND (Ground) <-> GND
  • MISO (Master Input Slave Output) <-> 11
  • MOSI (Master Output Slave Input) <-> 12
  • SCK (Serial Clock) <-> 13
  • SS (Slave select) <-> 10

This is how to connect it, but I don't have MISO and MOSI on my board. Countless of people have connected this board via SPI, yet there isn't a diagram or instructions on how to. The instructions above are for a slight variant of this board, but have the same chip and all. There are pins on the front of the board unsoldered, but they don't say MISO or MOSI, let alone, SS, SCK, and the 5V VCC

Posting a link to the datasheet of that board might help us to be sure.

That is literally the link for the datasheet for this model. I got it from here: ITEAD PN532 NFC MODULE - ITEAD Wiki
