APGRD001, Passive Keyless Entry (PKE) Reference Design

PKE Reference Design demonstrates a fully functional Passive Keyless Entry system. This solution contains 3 independent boards: Key Fob, Base Station and Receiver/Decoder. Base Station starts RF communication by sending out a 125Khz signal. Key Fob receives and decodes Low Frequency challenge from Base Station. If there is a match, Key Fob will transmit a 432Mhz signal back to Receiver/Decode. If Receiver/Decode recognizes Key Fob as a valid device it will send out a signal to unlock door
