Turn Off Module; Power Output - Quectel SC200L-EM Hardware Design

3.5.2. Turn off Module

Set the PWRKEY pin low for at least 1s, and then choose to turn off the module when the prompt window
comes up.
It can also be forced to restart by pulling down the PWRKEY key for a long time (more than 7 seconds).
The restart sequence diagram is as follows:

3.6. Power Output

SC200L supports the output of regulated voltages for peripheral circuits. During application, it is
recommended to use parallel capacitors (33pF and 10pF) in the circuit to suppress high-frequency noise.
