SI4432 RF Module

SI4432 433MHz RF Wireless Communication Module

Transceiver 1000 Meters 20dBm 240-930 MHz 3.6 V 256kbps Silabs EZRadioPRO

     It is a wireless communication transceiver module built with the EZRadioPRO Si4432 integrated circuit from Silabs. It can communicate in the ISM band between 240-930mhz frequencies at 1-20dbm power levels. It can communicate up to a distance of 1000 meters. It can receive signals with high sensitivity.

Warnings:

• The antenna must be in an open area away from metal parts, batteries and copper surfaces.
• The product must not be inside a metal box. If the antenna is attached to a metal surface, the communication distance drops greatly.
• If the product is used inside a metal box, the antenna must be moved outside the box.
• It must be supplied with a clean power source that can provide over 3.3V 200mA. Sufficiently large capacitance support must be added to suppress fluctuations on the supply line.
• Supplying it with a battery is not a problem. Lithium batteries can be used. With battery supply, the reduction of noise improves the operation of the product.
• At low communication speeds, the communication distance increases.
