{"title":"RFID Qwiic Reader for ID Innovations Modules","handle":"sparkfun-rfid-qwiic-reader","url":"/products/sparkfun-rfid-qwiic-reader","description":"This Qwiic RFID reader breakout makes it much easier to add low-frequency 125kHz RFID scanning to a project. It is designed for ID Innovations ID-3LA, ID-12LA and ID-20LA reader modules, converting the module output into simple I2C commands so your main microcontroller does not need to handle serial parsing.An onboard ATtiny84A captures each scanned six-byte ID tag, adds a timestamp and stores up to 20 unique scans in an internal stack. Power and I2C communication are handled through the Qwiic connector at 3.3V, while the INT pin can be connected if you want an interrupt signal when a card is read.The board includes a red read LED and magnetic buzzer for scan feedback, plus a jumper to disable the buzzer for quiet installations. Standard 0.1-inch pins are also broken out for breadboard prototyping or traditional soldered connections.Arduino and Python / MicroPython / CircuitPython libraries are available, along with hardware files, hookup guidance and RFID tutorials. Note that most ID Innovations modules have an internal antenna, but ID-3XX modules will likely require an external antenna; check the module datasheet before choosing your reader.Features:Smart data handling: Captures the six-byte ID tag, attaches a timestamp and stores scan data for I2C retrieval.Internal scan stack: Safely holds up to 20 unique scans at once.Qwiic I2C connection: Supplies 3.3V power and I2C communication without soldering.Interrupt option: INT pin can indicate when an RFID card has been read.Audio and visual alerts: Red LED and magnetic buzzer provide immediate scan confirmation.Silent operation option: Jumper cut disables the buzzer.Breadboard friendly: Standard 0.1-inch spaced pins are broken out alongside the Qwiic connectors.Address configuration: Default I2C address is 0x13, with a jumper available to switch to 0x14, and is software-configurable.Specifications:Voltage In: 3.3V via QwiicQwiic Connector: 2x Qwiic ConnectorRFID module footprint: ID-Innovations RFID Read Module FootprintDefault I2C Address: 0x13 to 0x14LED: PowerLED: ReadBuzzer: Magnetic BuzzerJumper: Interrupt: INTJumper: Buzzer: BUZZERJumper: Connects the I2C Pull-Up: I2CJumper: Change Default I2C Address: ADRBoard Dimensions: 1.00\" x 1.24\" (25.4mm x 31.5mm)Weight: 0.23oz (6.6g)A multiplexer is required to communicate with multiple RFID readers on a single I2C bus, such as when building multi-reader access control, tracking or interactive display projects.","vendor":"SparkFun","product_type":"RFID Reader Breakout","in_stock":true,"options":[],"variants":[{"id":15736,"title":"Default Title","sku":"SF-SEN-15191","mpn":"SEN-15191","price":43.35,"on_sale":false,"in_stock":true,"available_quantity":2}]}
