ماژول WIRELESS 433 SI4432

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.
