The Xadow NFC v2 features the most popular NFC chip-set on the market – a highly integrated transceiver module PN532. This chip set is very powerful and can be seen in most of smartphones and NFC devices. It can be used to read and write to tags and cards, acting like NFC tags. Currently we’ve developed Arduino libraries to support reading and writing to MIFARE Class and MIFARE Ultralight Card.

The board also adopts the new 11 PIN Xadow connector to improve the flexibility of module connections.

Near Field Communication (NFC)

Near Field Communication (NFC) is the set of protocols for the communication of electronic devices that are close proximity to each other (typically 10cm or less). Full NFC devices usually have three working mode:

Card Emulation: typically used in entrance card, or in smartphones to let them acts like smart cards to perform payment process or ticketing
Reader/Writer Mode: used to read the information stored in the NFC tags
Peer-to-peer Mode : used for data exchanging between devices

Features:

Open source and modular design
Slim and small
Built-in 11 PIN Xadow Connectors for full flexible connection with other Xadow Modules
Stackable, chainable and sewable with other Xadow Modules
