SI4432 wireless rf module adopts Silicon Laboratories SI4432 B1 version chip design . SI4432 is a highly integrated wireless transceiver chip ISM frequency. It has a very high receiver sensitivity (121 dBm), maximum + 20 dBm output power, known as the "king of wall," This module uses the SI4432 - B1 version of IC design, stable and reliable performance, no crash. Lead-free design, the product through RHOS testing.
