PN532開發板，評估板
產品介紹：
PN532是NXP最近推出的一款NFC芯片，支持讀卡器模式和卡模式（需要卡芯片Smart MX），支持TypeA、TypeB、TypeC三個標準，內部帶一個MCU51，支持命令方式，可以直接跟PC機串口連接就成為一個RFID讀卡器，簡單方便，成本低，性能好，是RFID發展的一個趨勢。
讀卡器通過串口和電腦連接，上位機可以使用libnfc，libnfc是一個開源的軟件，功能特別強大，實現了很多nfc的功能。
電路板全部採用機器焊接，外觀整齊漂亮，質量穩定可靠。
絕對不會出現虛焊和短路。市面上一些採用手工焊接的PN532（QFN封裝）電路板，由於QFN封裝的原因經常發生虛焊和短路現象。
電路板將PN532的所有引腳都引出來，方便二次開發評估，包括smartMX芯片的接口也引出來。
電路板天線經過數學公式的計算，達到最佳的匹配效果，3.3v供電，最遠的讀卡距離可以達到5CM！！！

libnfc的應用，讀取mifare卡片：
沒有放卡片的時候出來：
p2p通信：
兩個pn532之間可以進行p2p通信，該功能是nfc的一個重要應用，把兩個pn532接到電腦，並且放在一起，用libnfc軟件測試，一個做initiator，一個做target：
