## Description

This kit gives you the core hardware needed to start reading 125kHz RFID tags over I2C, without hunting for a separate reader module, antenna or wiring up a complex circuit. The box includes a SparkFun RFID Qwiic Reader, an ID-12LA RFID reader module, two 125kHz RFID cards and a 100mm Qwiic cable.Plug the ID-12LA module into the breakout, connect the Qwiic cable to a Qwiic-enabled development board, and you are ready to scan. The reader handles decoding and storage, capturing each scanned six-byte ID tag with a timestamp and keeping up to 20 unique scans on an internal stack for retrieval over simple I2C commands.The board provides 3.3V power and I2C communication through Qwiic, with standard 0.1-inch spaced pins also broken out for breadboard or soldered builds. A red LED and magnetic buzzer give immediate scan feedback, and the buzzer can be disabled by cutting its jumper.Arduino and Python libraries are provided, along with the hardware files, hookup guide and ID-12LA datasheet. If you want to use the interrupt signal, you will need to solder or otherwise connect the interrupt pin; multiple readers on one bus require a Qwiic multiplexer.Features:Complete RFID bundle: Includes RFID Qwiic Reader, ID-12LA reader module, two 125kHz RFID cards and a 100mm Qwiic cable.125kHz RFID scanning: Designed for reading compatible 125kHz RFID cards.I2C Qwiic connection: Supplies 3.3V power and communication through the Qwiic connector.Smart data handling: Captures the six-byte ID tag, adds a timestamp and stores scans internally.Scan storage: Internal stack safely holds up to 20 unique scans at once.Audio and visual alerts: Includes a red LED and a magnetic buzzer for immediate scan confirmation.Buzzer control: A jumper cut disables the buzzer for silent projects.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.Software-configurable address: I2C address is fully software-configurable.ID-12LA interface support: Supports ASCII, Wiegand26 and Magnetic ABA Track2 data formats.Library support: Arduino Library and Python Package are available.Specifications:SparkFun RFID Qwiic Reader - Voltage In: 3.3V via QwiicSparkFun RFID Qwiic Reader - Qwiic Connector: 2x Qwiic ConnectorSparkFun RFID Qwiic Reader - RFID module footprint: ID-Innovations RFID Read Module FootprintSparkFun RFID Qwiic Reader - Default I2C Address: 0x13 to 0x14SparkFun RFID Qwiic Reader - LED: PowerSparkFun RFID Qwiic Reader - LED: ReadSparkFun RFID Qwiic Reader - Buzzer: Magnetic BuzzerSparkFun RFID Qwiic Reader - Jumper Interrupt: INTSparkFun RFID Qwiic Reader - Jumper Buzzer: BUZZERSparkFun RFID Qwiic Reader - Jumper Connects the I2C Pull-Up: I2CSparkFun RFID Qwiic Reader - Jumper Change Default I2C Address: ADRSparkFun RFID Qwiic Reader - Board Dimensions: 1.00" x 1.24" (25.4mm x 31.5mm)SparkFun RFID Qwiic Reader - Weight: 0.23oz (6.6g)ID-12LA RFID Reader Module - Frequency: 125kHz (nominal)ID-12LA RFID Reader Module - Card Format: EM 4001 or compatibleID-12LA RFID Reader Module - Read Range: Up to 120mmID-12LA RFID Reader Module - Encoding: Manchester 64-bit, modulus 64ID-12LA RFID Reader Module - Power Requirement: 2.8VDC - 5VDC @ 35mAID-12LA RFID Reader Module - RF I/O Output Current: ±200mA PKPKID-12LA RFID Reader Module - Certification: CE, C-TICK, ROHS, FCCA handy kit for adding RFID card scanning to Qwiic-based Arduino, Python and microcontroller projects, access-control prototypes and interactive builds.
