433MHz RF Communication Module Wireless Transceiver Board 100mW SPI Interface RF4432PRO
Introduction:
The RF4432PRO module uses the Silicon Lab Si4432 device, a highly integrated wireless ISM band transceiver chip. Extremely low receive sensitivity (-121dBm), combined with industry-leading +20dBm output power, ensures 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.
