The Ground of power and signal need to be GND. Ground signal connection is not complete will have
an impact on the performance of the product. In addition, there are a total of 28 (63~90) heat sink and
fixed ground pad.

Hardware power on/off
Module second pin is the Power on/off key.
Pulling down the PWRKEY continuously, the module will
boot. Releasing the PWRKEY, the module will shutdown. There is internally pulled-up resistor.
If using
the power on the boot form, and the PWRKEY is grounded directly. If you do not need to power on the
boot, you can control the PWRKEY to achieve. Typical circuit is shown in figure 3-2.
