Original factory! 1km 868MHz FSK / GFSK RF wireless transceiver modules RF4432PRO

  
Product Description

RF4432Pro is the upgraded version of RF4432. The stability, anti-interference has been much improved with the shielding case and improvement of circuit.

 

RF4432Pro adopts Silicon Lab Si4432 RF chip, which is a highly integrated wireless ISM band transceiver. The features of  high sensitivity (-121 dBm), +20 dBm output power, 10PPM crystal, and good RF matching circuit make this module work well in hot/cold environment with reliable communication and long distance.
