Qwiic Dynamic NFC/RFID Tag Hookup Guide
The SparkFun Qwiic Dynamic NFC/RFID Tag features the ST25DV64KC dynamic Near Frequency Communication (NFC) / Radio Frequency Identification (RFID) tag IC from STMicroelectronics©. The ST25DV64KC offers 64-kBit (8-kBytes) of EEPROM memory which can be accessed over both I2C and RF (NFC)! It's a state-of-the-art tag which conforms to ISO/IEC 15693 or NFC Forum Type 5 recommendations. You can read and write the tag's memory using NFC even while the tag is powered down or disconnected!
In this guide we'll go into some detail on the ST25DV64KC IC and other hardware on this Qwiic breakout, how to assemble it into a Qwiic circuit and then install the SparkFun ST25DV64KC Arduino Library.
To follow along with this guide you will need a microcontroller to communicate with the Qwiic Dynamic NFC/RFID Tag. Below are a few options that come Qwiic-enabled out of the box:
If your chosen microcontroller is not already Qwiic-enabled, you can add that functionality with one or more of the following items:
You will also need at least one Qwiic cable to connect your sensor to your microcontroller.
If you aren't familiar with the Qwiic system, we recommend reading here for an overview.
We also recommend taking a look at the following tutorials if you aren't familiar with the concepts covered in them. If you are using one of the Qwiic Shields listed above, you may want to read through their respective Hookup Guides as well before you get started with the Qwiic Dynamic NFC/RFID Tag.
