Key Fob Receiver Overlay Shield for WiPy

  • Adds Key Fob Receiver as an Overlay Shield For WiPy
  • 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 WiPy Devices and Adapters
  • Compatible with WiPy


The WPKF 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, WiPy I/O lines are asserted High for the duration of the remote button press. WiPy 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 WiPy Pins:
Key Fob Button 0 is Connected to WiPy GPIO0
Key Fob Button 1 is Connected to WiPy GPIO3
Key Fob Button 2 is Connected to WiPy GPIO4
Key Fob Button 3 is Connected to WiPy GPIO5
Key Fob Button 4 is Connected to WiPy GPIO14
Key Fob Button 5 is Connected to WiPy GPIO15
Key Fob Button 6 is Connected to WiPy GPIO16
Key Fob Button 7 is Connected to WiPy GPIO17


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 WiPy. This Overlay Shield REQUIRES a controller with Double-Row Headers on each side of the WiPy module interface. To use an overlay shield, WiPy devices are plugged into a controller, which has two rows of pins on each side of the WiPy module. This shield installs over the top of the WiPy, using the outer set of pins of the controller to make contact with the WiPy module. Please examine photos carefully to see how overlay shields are installed.

Key Fob remote control transmitters can be found here.
