The PKFR is a 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, Particle Photon I/O lines are asserted High for the duration of the remote button press. Particle 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 Photon/Electron Pins:
Key Fob Button 0 is Connected to Particle A0
Key Fob Button 1 is Connected to Particle A1
Key Fob Button 2 is Connected to Particle D2
Key Fob Button 3 is Connected to Particle D3
Key Fob Button 4 is Connected to Particle D4
Key Fob Button 5 is Connected to Particle D5
Key Fob Button 6 is Connected to Particle D6
Key Fob Button 7 is Connected to Particle D7
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 Particle Photon or Particle Electron. This Overlay Shield requires a ControlEverything.com controller with Double-Row Headers on Each Side of the Particle module interface. To use an overlay shield, Particle Photon/Electron are plugged into a ControlEverything.com controller, which has two rows of pins on each side of the Particle module. This shield installs over the top of the Particle Electron/Photon, using the outer set of pins of the ControlEverything.com controller to make contact with the Particle module. Please examine photos carefully to see how overlay shields are installed.
Key Fob remote control transmitters can be found here.
