The Qwiic RFID ID-XXLA is a simple board that pairs with and comes in a kit with, the ID-12LA and three RFID 125kHz cards to get you started integrating an I2C RFID solution into your project. 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 and we’ve included some example code that shows you just how to do it using the broken out interrupt pin. The ID-12LA module has a scan range of about 5-6 inches and the board includes a buzzer and LED that indicates that a card has been scanned. We’ve included a jumper to disconnect the buzzer in case the noise is too grating (but does not disconnect the LED), a jumper for the I2C pull-up resistors, an interrupt jumper, and finally an address jumper.
We do not plan to regularly produce SparkX products so get them while they’re hot!
