Gravity: I2C & UART NFC Module
psychokiller1888 2021-08-26 05:58:11 2418 Views1 Replies I just bought myself three of those NFC readers and hooked them up to an arduino micro. The tag that came along works just fine for reading and writting.
But.... I got 2 implants in my hand, one is a dual NFC tag, using Mifare Ultralight technology and the other one is a Walletmor payment chip. As a third candidate I have a Yubikey 4 NFC. All the three of them are red without any issue when using my Matrix Creator device and it's inbuilt nfc chip
That's where the difference stands, the Matrix Creator device uses a PN512 chip and the DFRobot Gravity module uses a PN532
The difference between them is we can access the chip directly with the PN512 though I2C but the PN532 uses a controller, which we access with I2C, SPI etc.
So, anyway to upgrade the controller to read my implants? As of now, I have 3 times 27 bucks paper holders sitting on my desk....

2021-09-05 07:08:45 I'm overwhelmed by the gigantic help recieved by the producer of these crap NFC modules and this community, quite impressive! Won't buy DFCrapbot in the near future psychokiller1888
