DFRobot NFC Module for Arduino - Black
Introduction Near Field Communications (NFC)£¬ a contactless£¬ Wi-Fi-lite style tech that could already be in your smartphone£¬ and could soon be a regular feature of your commute. Near Field Communications(NFC) is a set of short-range wireless technologies£¬ typically requiring a distance of 10cm or less£¬ for two devices such as smartphones or the similar things very close to each other to establish communication. Communication is also possible between a NFC device and unpowered NFC chips such as tags£¬ stickers£¬ key fobs and cards which do not require batteries. The NFC Module for Arduino is designed to extend this powerful feature for your project or application based on Arduino.It integrates a PN532 NFC controller from Philips.The driver interface for this product is UART interface of the microcontroller. So it's possible for you to test it via a USB to UART converter directly. On the other hand£¬ for the applications with microcontroller£¬ the module provides an event for your processor when detects the NFC tags£¬ stickers£¬ key fobs£¬ or cards via high speed serial uart. Applications - Contactless payment systems - Bluetooth and Wi-Fi connections - Social networking situations£¬ such as sharing contacts£¬ photos£¬ videos or files - Electronic identity documents and keycards - Smartphone automation and NFC tags Specification - Working Voltage: 3.3v or 5v - Host interface: UART - Default Band rate: 115200 bps - Integrate PN532 NFC controller - Supports ISO 14443A/MIFARE - Supports ISO 14443B in reader/writer mode only - Typical max operating distance for detecting NFC tags from 20 to 50mm depending on the antenna size of the tag - Serve for contactless communication at 13.56MHz Document: Please refer to download link;
