I'm using an Arduino to communicate with PN532 NFC controller and to drive a NeoMatrix according to the tag being read. I need to create many such units and make them wireless, while lowering the cost.
Is it possible to connect the PN532 NFC/RFID controller breakout board to XBee module directly through SPI and at the same time control the NeoMatrix (using a logic level shifter) without Arduino in the way?

Not that I am aware of.
An option would be to use one of the very small 6 pin processors (ATtiny) to do the SPI to async serial conversion. The code should almost the same as for the Arduino.
