PN532 Shield 3.3v or 5v?

Post by Anthrum »

Hello,

does the PN532 RFID shield, run at 3.3V, or does it have a built in level shifter? Using with a UNO.

I ask since the breakout runs at 3.3v.

thank you!

The shield runs on 5V, and has a 3.3V regulator and built-in level shifters on the input lines
