• Description
• The SparkFun RFID Qwiic Kit is a simple, yet all-in-one I2C based RFID starting point for the ID-3LA, ID-12LA, and ID-20LA readers. Simply plug a reader into the headers and use a Qwiic cable to connect to any Qwiic enabled development board, then scan your 125kHz ID tag and the unique 32-bit ID will be shown on the screen. This kit comes with everything you need to get started. The SparkFun RFID Qwiic Reader, an ID-12LA reader, a couple of RFID cards, and a cable to get you hooked up. Just plug this into any Qwiic enabled development board and you are good to go.
• Utilizing the onboard ATtiny84A, the Qwiic RFID takes the six byte ID tag of your 125kHz RFID card, attaches a time stamp to it, and puts it onto a stack that holds up to 20 unique RFID scans at a time. This information is easy to get at with some simple I2C commands. The unit comes with a read LED and buzzer, but don't worry, there is a jumper you can cut to disable the buzzer if you want.
• The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can't hook it up wrong.
