NFC Module 讀寫卡模組 PN532 近場通信讀寫模組 支援 Raspberry Pi

商品說明 PN532 NFC模組是基於PN532晶片，用於13.56MHz 的近場通信。該模塊配備板載天線，因此沒有外部天線線圈。它兼容SPI，IIC，UART接口進行通信。隨著NFC庫支持Arduino和我們所提供的Raspberry Pi的開發具有NFC功能的產品，使用起來是很方便的。 特點 最長的有效通訊距離為5厘米 支持SPI，IIC，UART接口切換。 可用於13.56M的非接觸式通信 兼容ISO14443 TYPE A和B類標準 出貨清單： 模組*1 RFID白卡*1 RC522鑰匙扣*1 PN532 NFC MODULE PN532 NFC module, as its name implies, is based on PN532 chip and used for 13.56MHz near field communication. The module is equipped with onboard antenna, thus no external antenna coil is needed. It is compatible with SPI, IIC and UART interface for communication. With NFC library support for Arduino and Raspberry Pi offered by us, it is quite convenient for development of products with NFC functions. Features Longest effective communication distance of 3 cm Supports switching of SPI, IIC and UART interface. Can be used for 13.56M non-contact communication Compatible with ISO14443 Type A and Type B standards Specifications IC NXP PN532 Operating Voltage 3.3V Power Supply Voltage 3.3~5.5V Max Supply Current 150mA Working Current(Standby Mode) 100mA Working Current(Write Mode) 120mA Working Current(Read Mode) 120mA Indicator PWR Interface SPI Interface, Std Raspberry Pi 20pins Interface
