I connected 0 0 together, but the connection seems just short the device and my Pi just restart itself after connected (or it won't start while connected with NFC board).

Our NFC board uses HSU: 0 0 The red light flickers a little bit but the module works. If you have problems, you could try a TTL USB module.

I set my NFC board to HSU - soldered 0 > 1 together and left the other as is. I think that set it to 0 0 for HSU. Prior to doing that, it seemed it was power up from the pi, and the Pi remained on. Now after soldering, it seems to draw too much from the Pi - the red power light on the pi dims if I use 3.3v or goes right out if I use 5v and the power LED on the NFC board doesn't light up. I've tried power adapters from 5v .5a to 5v 1.0amp. Any suggestions would be appreciated! What was the rating of the power supply you used with your Pi?

Read specs (<a href="http://www.elechouse.com/elechouse/index.php?main_page=product_info&cPath=90_93&products_id=2205" rel="nofollow">NFC Kit</a>) for more details. If you are unsure, use a TTL module. The board works on our Pi with and without TTL module.

I just wanted to know if it is safe to hook up PN532 NFC RFID module to 5V? I am new to EE but here (http://learn.adafruit.com/adafruit-ultimate-gps-on-the-raspberry-pi/using-uart-instead-of-usb) it mentions that it is safe to use 5V if the connected board has voltage regulator. Also here (http://learn.adafruit.com/adafruit-nfc-rfid-on-raspberry-pi/testing-it-out) it mentions that boards with no 5V level shifting are not safe to Raspberry PI. Does PN532 NFC RFID module has any of these? P.S. I am now waiting for my RPI and PN532 NFC RFID module to arrive. Trying to read up as much as I can. Great advice!
