Frequently Asked Questions

What is the operating voltage range for the ID-12LA RFID module?

The ID-12LA operates from a wide DC input range of 2.8V to 5V. This makes it directly compatible with both 3.3V logic systems (like ESP32 or Raspberry Pi) and standard 5V Arduino boards without requiring a level shifter.

What data output formats does the ID-12LA support?

The module outputs decoded tag data in three standard formats: ASCII text, Wiegand26 (a common access control protocol), and ABA Track2 (magnetic stripe emulation). The format is typically selected via the wiring configuration or internal settings.

What type of RFID tags are compatible with this reader?

The ID-12LA is designed to read passive RFID tags operating at 125kHz, specifically those compatible with the EM4001 standard. This includes many common low-frequency key fobs, cards, and disc tags used in access control systems.

How do I interface the ID-12LA with an Arduino or microcontroller?

Connect the module's VCC and GND to your power supply (2.8-5V). The DATA pin provides a serial TTL output. Connect this pin to a serial RX pin on your microcontroller. You can then read the tag ID directly via the serial port using the selected output format (e.g., ASCII).

What is the typical read range, and what affects it?

The maximum read range is up to 120mm (approx. 4.7 inches) under ideal conditions. The actual range can be influenced by the tag size, orientation, antenna alignment, and electromagnetic interference in the environment. Metal surfaces near the antenna will significantly reduce performance.
