An RF receiver module receives the modulated RF signal, and demodulates it. There are two types of RF receiver modules: superheterodyne receivers and superregenerative receivers. Superregenerative modules are usually low cost and low power designs using a series of amplifiers to extract modulated data from a carrier wave.
LPD433 (low power device 433 MHz) is a UHF band in which license free communication devices are allowed to operate in some regions. The frequencies correspond with the ITU region 1 ISM band of 433.050 MHz to 434.790 MHz.

Several classes of daughterboard modules exist: Receivers, Transmitters and Transceivers. Transmitter daughterboard modules can modulate an output signal to a higher frequency; Receiver daughterboard modules can acquire an RF signal and convert it to baseband; Transceiver daughterboard modules combine the functionality of a Transmitter and ...
