Frequently Asked Questions

What types of RFID tags are compatible with the ID-3LA module?

The ID-3LA reader is specifically designed for 125kHz Low Frequency (LF) tags that use the EM4001 protocol and 64-bit Manchester encoding. It is compatible with a wide range of EM4100-family transponders, including key fobs, cards, and glass tags that adhere to this standard.

How do I interface the ID-3LA module with an Arduino or Raspberry Pi?

You can interface the module via its TTL serial (ASCII) output by connecting the TX pin of the module to an RX pin on your microcontroller. For Wiegand26 output, connect the DATA0 and DATA1 lines to digital input pins. Ensure the module's power supply is within the 2.8V to 5V range, matching your system's logic level.

Does the module include an antenna, and what is the maximum read range?

No, the ID-3LA module requires an external 125kHz antenna coil to be connected to its RF I/O pins. The achievable read range, up to approximately 30mm, depends on the size, geometry, and tuning of this external antenna. Proper antenna design and matching are critical for optimal performance.

What is the difference between the ASCII, Wiegand26, and ABA Track2 output formats?

ASCII mode outputs the tag's ID as a plain text serial string. Wiegand26 is a common 26-bit binary format used in access control systems, comprising 24 data bits and 2 parity bits. ABA Track2 format emulates the data from a magnetic stripe card's second track, useful for legacy system integration.
