Breakout Wiring

This part of the tutorial is specifically for the Breakout board. We show how to use it with SPI. The breakout also

supports TTL serial and I2C but we don't have a tutorial for using it that way as SPI is the most cross-platform method

to communicate

If you're using the shield, check the next page

Wiring the Breakout for SPI

The PN532 chip and breakout is designed to be used by 3.3V systems. To use it with a 5V system such as an Arduino,

a level shifter is required to convert the high voltages into 3.3V. If you have a 3.3V embedded system you won't have

to use the shifter of course!

To begin, we'll solder in the header to the breakout board. You'll need two small 3-pin pieces of header and one 8-pin

piece. You can break these off of a large piece.
