Spent some time with the device and have been reading many troubleshooting guides for this guide. Regardless of mode, it doesn't show up. Even after editing the Pi config file to allow all the connection types, it did not work. No usage guide was provided with the guide either.SPI: Did not workUART: Did not workI2C: No sign of lifeIt's just good for a red LED, I guess.

Please please please make sure you double check that this is exactly what you need and that it is compatible with whatever you intended purpose is. The products works perfect as described, but you can run into issues if you are unsure what radio frequencies you are trying to interact with and with what medium (rasp pi, arduino) you are trying to connect it with. I was using a raspberry pi 3B+ and ran into compatibility issues, so please review any documentation for projects out there to make sure this will work for you.

Bought this as a cheap way to see if an NFC project was feasible, and it works using both the included tags and some NTAG213 stickers found elsewhere on amazon. I soldered in one of the included 4-pin headers, and then used that to connect an FTDI TTL-232R-5V usb-to-ttl-serial cable. It then comes right up and works with libnfc and the libnfc examples, after putting the proper serial port into /etc/nfc/libnfc.conf . I'll be ordering a few more.Two little things that didn't bother me: only has a 4-pin connector, so I had to put a custom matching 4 pin connector onto the FTDI cable. If this had a compatible 6-pin connector, I could have used an unmodified FTDI cable or other usb-ttl-serial adapter with the common 6 pin header. The set of three wires were not included in my package.

I bought a PN532, expecting it to work right after soldering. I've seen videos of what this chip can do; it *should* have a tolerance of 5cm to read from, and should be able to read 14443 ISO tags as well as Mifare classics. And it does! At least, when you get the board to connect and STAY CONNECTED. After about four dozen attempts of rewiring, trying different wires and testing the board (and my Arduino) for issues, all I got was a brief connection to the PN532 before it sputtered out and died on me. I even attempted to resolder the board connectors (which turned out to be a bad idea), and ended up with what is now a defunct board, despite the board looking perfectly fine.EDIT: It turns out that the board was fine; rather, the Arduino I was working with had faulty data pins. Works just as advertised. Great board.
