SX1231H Description

The SX1231H is a highly integrated RF transceiver capable of operation over a wide frequency range, including the 433, 868 and 915 MHz license-free ISM (Industry Scientific and Medical) frequency bands. Its highly integrated architecture allows for a minimum of external ponents whilst maintaining maximum design flexibility. All major RF munication parameters are programmable and most of them can be dynamically set.
