Key Fob Receiver Overlay Shield for Onion Omega

  • Adds Key Fob Receiver as an Overlay Shield For Onion Omega 2 & 1
  • 1, 2, 3, 4, 5, 8-Button Remote Control Compatible
  • Pairing Button with Valid Receive LED
  • Up to 750 Foot Range with 8-Button Key Fob
  • 418/433 MHz Operation with Integrated LICAL Decoder
  • Designed for Onion Omega Devices and Adapters
  • Compatible with Onion Omega 2 and Onion Omega 1


The OOKF is a Onion Omega Key Fob Receiver/Decoder shield compatible with Linx Technologies MS Series Key Fob Transmitters operating at 418/433MHz (1, 2, 3, 4, 5, 8-Button Transmitters Available Separately). This device is capable of receiving button presses from a remote control up to 750 feet away (when using the 8-Button remote). When a remote control button is pressed, the on-board Valid LED illuminates. In addition, Onion Omega I/O lines are asserted High for the duration of the remote button press. Onion Omega I/O lines return to a low state when the remote control button is released.

Includes RP-SMA Antenna.

The On-Board LICAL Key Fob Decoder is Mapped to the following Onion Omega Pins:
Key Fob Button 0 is Connected to Particle GPIO0
Key Fob Button 1 is Connected to Particle GPIO1
Key Fob Button 2 is Connected to Particle GPIO6
Key Fob Button 3 is Connected to Particle GPIO7
Key Fob Button 4 is Connected to Particle GPIO8
Key Fob Button 5 is Connected to Particle GPIO12
Key Fob Button 6 is Connected to Particle GPIO13
Key Fob Button 7 is Connected to Particle GPIO14


NOTE: Key Fob remotes are security encrypted, and must be paired with the controller prior to use. This is an Overlay Shield and does NOT directly plug into the Onion Omega. This Overlay Shield REQUIRES a controller with Double-Row Headers on each side of the Onion Omega module interface. To use an overlay shield, Onion Omega devices are plugged into a controller, which has two rows of pins on each side of the Onion Omega module. This shield installs over the top of the Onion Omega, using the outer set of pins of the controller to make contact with the Onion Omega module. Please examine photos carefully to see how overlay shields are installed.

This adapter plugs into any of our controllers and adapters manufactured for Onion Omega.
