5.2.2 RESET_N
The RESET_N pin is used to reset the N58 module. When the module is working properly, inputting a
low-level pulse for more than 50 ms at the RESET_N pin can trigger the reset process of the module.
RESET_N is connected to VBAT internally by using a 20 kΩ pull-up resistor. Leave this pin floating if it
is not used.

If the 1.8 V/2.8 V/3.0 V IO system is used, it is recommended that a triode be used for isolation. For
details about the design, see the following figure.
