Based on Silicon Labs' SI4432 wireless transceiver chip design, it is a compact, low-power, and long-distance wireless transceiver module. The module adopts single-chip architecture, and the periphery adopts high-precision crystal, high-Q Murata inductor, small volume but high-capacity filter capacitor. All SMD components are used, and the interface is encapsulated with standard spacing stamp edge.
