“Easy to use, decent library, works with everything i've tried so far. Note that (currently) the adafruit guide showing how to assemble the breakout board for SPI shows a v1.3, and that although there is a 5V pin on the v1.6, the data lines still use 3.3V, so the 4050 level shifter (included) is still needed if you're using an arduino and SPI - setting it up in the exact same way as the v1.3 guide with the same code still works for me. Would recommend getting some more NFC/RFID tags, in various shapes and sizes.”
“This works really well with the raspberry Pi with either SPI or UART with the Mifare Classic cards. It does support the Mifare Ultralight but I am having trouble reading the data from it. Other than that I cannot complain.”
