مشخصات ماژول SI4432 Wireless Transceiver 433MHz
This module uses the latest version of Silicon Labs’ highly integrated wireless ISM transceiver chip SI4432. The frequency range is 240 ~ 930MHz, with extremely high receiving sensitivity (-117dBm) and transmitting power (+ 20dBm), which greatly improves the penetration ability and transmission range. When the output power is + 20dBm, the communication distance is more than 1000 meters . Users do not need to know the relevant knowledge of the radio to use this module to easily develop stable and reliable wireless related products.
