RFID Reader Module - ID-3LA (125 kHz)

A no-contact, low-voltage 125kHz RFID reader module supporting ASCII, Wiegand26, and Magnetic ABA Track2 serial data formats at a range of 3cm.


Description

RFID (radio-frequency identification) is the wireless non-contact use of radio-frequency electromagnetic fields for the purposes of identifying and tracking tags attached to objects. With this ID-3LA RFID Reader module from ID Innovations, you can read standard 125kHz tags and cards at a range of 30mm to bring wireless identification to your next project! Simply power the module, present a compatible card to a compatible antenna, and the ID-3LA outputs a clean serial string containing the card's unique ID. The module will handle all of the complex RF decoding internally, so all your microcontroller needs to do is listen for incoming serial data.

Simple 125kHz RFID

Despite its small footprint, this module is highly adaptable to different hardware setups and communication standards.

  • Multi-Format Support: The RFID module supports ASCII, Wiegand26, and Magnetic ABA Track2 data formats, enabling easy interfacing with a wide range of microcontrollers and existing security systems.
  • Low-Voltage Operation: Operating on a flexible 2.8V to 5.0V range, this version offers a lower input voltage than older alternatives, making it ideal for battery-powered setups and 3.3V systems.

Please be aware that this module features a 2mm pin spacing, which is slightly tighter than standard 0.1-inch breadboard spacing. We offer multiple breakouts designed exclusively for connecting to ID Innovations RFID modules (see the right-hand column or the Similar Items section below for options). Additionally, the ID-3LA relies entirely on an external antenna, giving you the freedom to choose an antenna that matches the physical constraints and read-range requirements.

With its broad data-format compatibility and energy-efficient design, this module provides a reliable way to add contactless tracking to your hardware.
