3.8. Reset the Module
The RESET_N can be used to reset the module. The module can be reset by driving the RESET_N to a
low level voltage for 150~460ms. As the RESET_N pin is sensitive to interference, the routing trace on the
interface board of the module is recommended to be as short as possible and totally ground shielded.
