描述

Gravity: UART & I2C NFC Module 近場通訊模組 支援串口與IIC通訊 也支援 Micro:bit

Gravity: UART & I2C NFC Module 近場通訊模組 採用 NXP PN532 進口高集成NFC通信晶片,支援市面上常見的各類MIFARE Classic S50/S70系列(即M1卡)和NTAG21x系列等工作頻率在13.56Mhz的NFC電子標籤或卡片。在繼承之前版本大PCB天線所帶來較大通信距離優點的基礎上,升級版採用Gravity標準的PH2.0-4P介面,除了讓接線更方便,在保留UART的基礎上額外複合了I2C,通過開關輕鬆切換兩種不同的介面,使用更靈活。當使用UART串口時,可以利用市面上常見的USB to UART轉換器和協力廠商上位機軟件輕鬆讀寫操作各類NFC卡。當使用I2C介面時,則可用於Arduino、micro:bit、FireBeetle ESP32、FireBeetle ESP8266等各類3V3/5V主控系統。

近場通訊簡介

近場通信(Near Field Communication,NFC),又稱近距離無線通信,是一種短距離的高頻無線通信技術,允許電子設備之間進行非接觸式點對點數據傳輸(在十釐米內)交換數據。這個技術由免接觸式射頻識別(RFID)演變而來,並向下相容RFID,最早由Sony和Philips各自開發成功,主要用於手機等手持設備中提供M2M(Machine to Machine)的通信。由於近場通訊具有天然的安全性,NFC技術被廣泛用於POS機移動支付、公交卡、銀行卡、門禁卡、飯卡、水卡等多種場合。

Gravity: UART & I2C NFC Module

Gravity: UART & I2C NFC Module adopts NXP PN532, a highly integrated NFC communication controller, which supports various types of NFC smart cards or tags like the commonly used MIFARE Classic series and NTAG series in the market. Apart from the large PCB antenna design of better communication area and distance , the upgraded version joins the Gravity family by adopting a standard Gravity PH2.0-4P interface with I2C & UART composite rather than 2.54mm headers, making the wiring more convenient. A switch is added for conveniently switching between these two interfaces. When using the UART, you can easily read and write various NFC cards by using the common USB to UART converter and PN532 compatible PC software. When using the I2C interface, it can be used for various 3V3/5V controller such as Arduino, micro:bit, FireBeetle ESP32 and FireBeetle ESP8266.

About NFC

Near Field Communication (NFC), also known as short-range wireless communication, is a short-range high-frequency wireless communication technology that allows non-contact point-to-point data transmission (within ten centimeters) to exchange data between electronic devices. . This technology evolved from contactless radio frequency identification (RFID) and is backward compatible with RFID. It was first developed by Sony and Philips, and is mainly used to provide M2M (Machine to Machine) communication in handheld devices such as mobile phones. Because of the natural security of near field communication, NFC technology is widely used in POS mobile payment, bus cards, bank cards, access cards, water cards and other occasions.
