1.  Make sure that customers’ PCB design provides sufficient cooling for the module: proper mounting, 
heatsinks, and active cooling may be required depending on the integrated application. 
2.  In order to protect the components from damage, the thermal design should be maximally optimized 
to  make  sure  the  module’s  internal  temperature  always  maintains  below  105°C.  Customers  can 
execute AT+QTEMP command to get the module’s internal temperature.
