Item Overview:
The RF4432X1 module uses the Silicon Lab Si4432 device, a highly integrated wireless ISM band transceiver chip. Extremely low receive sensitivity (-121 dBm), combined with industry-leading output power of 20 dBm, guarantees extended range and improved link performance. At the same time, built-in antenna diversity and support for frequency hopping can be used to further expand the range and improve performance.
