This RFID Receiver for Particle Photon makes it easy to interface RFID cards, fobs, tags, and stickers into your next IoT cloud automation application.

Simply swipe a RFID device across the sensor and read the code into the Particle Photon at 9600 baud (Bd). The SCI2CU includes an integrated I2C port for easy expansion to the entire I2C Product Line.

This design includes the popular EM18 RFID receiver, greatly simplifying software development.

This product includes a 1 ft cable for remote mounting of the RFID reader.

Based on availability, we will also include a RFID device for testing (a RFID Card, FOB, Tag, or Sticker).

This device makes use of the UART receive line, and should not be used with overlay shields.
