Hi, today I received my Nfc arduino board from china.
Here are the first picture and caracteristics:
-> Atmega 328
-> pn532 connected by uart
-> antenna designed for the NFC ring (but it's need some modifictions for the according circuit)
-> FT232 (USB to UART)
The other caracteristics are the same than the arduino uno (3v3/5 v output,... SPI, I²C, UART)
-3cm for normal card tag
-2cm for badge tag
-1cm for the nfc ring....
I thing the according circuit isn't as good as the simulation so I expect a bigger reading distance with the version 2. But with this configuration it's still better than the PN532 shield with my NFC rings (normal ring) :)
The version 2 (WIP) will have:
-> uhl connector for a deporting antenna
-> Bluetooth loow energy module
-> MSP430 proc (not sure)
What do you thing about that? :)
