Product Descriptions
S14432 wireless module, which uses Silicon Labs' highly integrated wireless ISM transceiver chip SI4432. The frequency range is 410~525MHz (default), with extremely high receiving sensitivity (-117dBm) and transmitting power (+20dBm), greatly improving penetration capability and transmission range. When the output power is+20dBm, the open and unobstructed communication distance is over 1000 meters.
