still a risk of damage)；
Try to stay away from some physical layers such as TTL protocol at 2.4GHz , for example: USB3.0；

The mounting structure of antenna has a great influence on the performance of the module. It is necessary to ensure

that the antenna is exposed, preferably vertically upward. When the module is mounted inside the case, use a good
antenna extension cable to extend the antenna to the outside；
The antenna must not be installed inside the metal case, which will cause the transmission distance to be greatly

weakened.

Si4463+PA+LNA，same drive way as SI4463，user can refer to SI4463 datasheet.

GPIO0 \ GPIO1 \ GPIO2 \ GPIO3 are configurable I/O ports for various application， see more in SI4463 datasheet.It can be

floated when not used.
IRQ pin can also be disconnected. The SPI query mode can be used to obtain the interrupt status. However, it is recommended to

use the external interrupt of the MCU.
SPI communication rate should not be set too high, usually around 1Mbps.

Please refer to "Operating Modes and Timing" for SI4463 status switch ， the switch between TX and RX should be through

Ready, can not be switched directly.
Re-initialize register configuration when the chip is idle for higher stability.

For controlling GPIO2 ,GPIO3 externally，pin status is as follows：

In tx mode：GPIO2 = 0; GPIO3 = 1;
In rx mode：GPIO2 = 1; GPIO3 = 0;
If the SI4463 is required to control itself, the mode of the configuration pins can be as follows when the program
is initialized:
SI44XX_GPIO_CONFIG( 0, 0, 32|0x40, 33|0x40, 0, 0, 0 );
