Description:RF4432 Wireless Transceiver Module is a single chip wireless ISM transceiver and a part of the EZRadioPRO™ family. The EZRadioPRO family contains a complete line of transmitters, receivers, and transceivers for choosing the optimal wireless part of the application. The Si4432 covers continuous frequency from 240 to 930 MHz with adjustable output power of up to +20. Because of the high level of integration, it provides reduced BOM cost while simplifying the overall system design. The ultra low receives sensitivity (–118) coupled with +20 dBm output power ensures extended range and improved link performance. Also, it has other features such as an automatic wake-up timer, low battery detector, 64 byte TX/RX FIFOs, automatic packet handling, and preamble detection reduces overall current consumption and allow the use of lower-cost system microcontrollers. By having an integrated temperature sensor, general purpose ADC, power on-reset (POR), and GPIOs, it's more economical and tiny size.RF4432Pro is the upgraded version of RF4432. By improving chip circuits and shielding case, its stability and anti-interference has been much improved. The features of high sensitivity (-121 dBm), +20 dBm output power, 10PPM crystal, and good RF matching circuit enable it to work well and reliably in any climate, in hot/cold environment for long distance.
