Module
Hardware circuit for RESET# (option 3)
GPIO is not high-impedance when the host is powered off.
Use only one N-MOSFET, in this case the logic of RESET# and GPIO1 is reversed.

As the RESET# signal is relatively sensitive, it is recommended to install a 33 pF
capacitor near to the M.2 pin.

Triggering the RESET# signal will lead to loss of all data in the module. It
will also disconnect the module from the network resulting in a call drop.
