Application Notes 1, around the antenna must be open, away from the battery, metal, etc., PCB copper plating around the prohibition of the antenna, if necessary, PCB and antenna overlap part of hollowing out or punch. 2, when the design of the product on the metal shell, metal cabinet, you must use the antenna feeder signal from the antenna leads to an external SMA antenna or suction cup antenna, otherwise the signal is shielded metal housing distance greatly reduced distance requirements, can Use a high-gain antenna. 3, power supply design. Power is the heart of the system, the design should focus on consideration. Si4432 wireless module recommended operating voltage 3.3V, transient current can provide more than 200mA. 4, using DCDC, LDO buck, but also consider the impact of ripple and surge current. The ripple can be handled by the LC network where the module is connected to the power supply; inrush current can be handled with large capacitors. 5, if the use of battery-powered, should consider the battery transient current is sufficient, it is recommended lithium batteries Ni-MH battery is not recommended with dry batteries. 6, the software design, should make full use of packet communication, communication set the lower the rate, the farther away. 7, when using a communication rate other than the DEMO program communication, the application parameter calculation tool to recalculate communication parameters. And according to their product communication requirements, appropriate adjustments.
