This RFID tag is really unique: it works with mobile phones just like other RFID tags, but you can reprogram it over I2C. The tag shows up as an ISO/IEC 15693 (13.56MHz) chip which is readable by phones and tablets. This could be interesting in situations where you want a tag that can be re-written dynamically when connected to a controller. For example, we did a test where we had a microcontroller write different URLs a few seconds apart, and the mobile phone detected the different URLs one after the other.／這個RFID標籤非常獨特：它像其他RFID標籤一樣適用於手機，但你可以通過I2C重新程式設計。標籤顯示為 ISO/IEC 15693 （13.56MHz） 晶片，手機和平板電腦均可讀取。在您希望在連接到控制器時可以動態重寫的標記的情況下，這可能很有趣。例如，我們做了一個測試，讓微控制器在幾秒鐘內寫入不同的URL，手機一個接一個地檢測到不同的URL。。
Note that the most popular hobby RFID reader/writer chips like the PN532 do not support ISO15693 so you cannot use those to read the ST25DV tag once programmed! We used both Apple and Android phones with success to read the tags.／請注意，最流行的業餘愛好RFID讀取器/寫入器晶元（如PN532）不支援ISO15693，因此一旦程式設計，您就無法使用這些晶片來讀取ST25DV標籤！我們成功地使用Apple和Android手機來讀取標籤。
According to the datasheet, one can even use it as an 'I2C to RFID' transfer system to wirelessly send and receive data from mobile devices (you'll need to write a custom app for that kind of project, though).／根據數據表，甚至可以將其用作「I2C到RFID」傳輸系統，以無線方式從行動裝置發送和接收數據（不過，您需要為此類專案編寫自定義應用程式）。
ST has written a handy library that you can easily use to write NFC URLs to the chip over I2C. You cannot use an Arduino UNO (ATmega328p) with the ST25DV library, there's not enough RAM. Please use a Metro M0 or other SAMD chip (or better) to communicate with the ST25DV. There's no Python or CircuitPython library for this chip at this time, only Arduino.／意法半導體編寫了一個方便的庫，您可以輕鬆地使用它通過I2C將NFC URL寫入晶元。您不能將Arduino UNO（ATmega328p）與ST25DV庫一起使用，沒有足夠的RAM。請使用Metro M0或其他SAMD晶元（或更好）與ST25DV通信。目前這個晶元沒有Python或CircuitPython庫，只有Arduino。
To make connections easy, our breakout contains an ST25DV04 chip, support circuitry and even a PCB trace antenna. There's standard 0.100”/ 2.54mm pitch headers for use with a breadboard. Should you wish to avoid soldering, the breakout also includes our Stemma QT connectors (SparkFun Qwiic compatible). Using these handy connectors you can simply plug in the sensor and get rolling with your project. QT Cable is not included, but we have a variety in the shop.／
為了簡化連接，我們的分線器包含一個ST25DV04晶元，支援電路，甚至一個PCB走線天線。有標準的0.100"/ 2.54mm間距針座，可與試驗板一起使用。如果您希望避免焊接，分線器還包括我們的Stemma QT連接器（相容SparkFun Qwiic）。使用這些方便的連接器，您只需插入感測器即可開始您的專案。QT電纜不包括在內，但我們在商店裡有各種各樣的電纜。
