Quectel M10 Hardware Description

M10 Hardware Design
following URC will be presented:
UNDER-VOLTAGE WARNNING
If the voltage ≥ 4.5V, the following URC will be presented:
OVER-VOLTAGE WARNNING
The uncritical voltage range is 3.4V to 4.6V. If the voltage ≥ 4.6V or ≤ 3.4V, the module will be
automatic shutdown soon.
If the voltage ≤ 3.4V, the following URC will be presented:
UNDER-VOLTAGE POWER DOWN
If the voltage ≥ 4.6V, the following URC will be presented:
OVER-VOLTAGE POWER DOWN
After this moment, no further more AT commands can be executed. The module logs off from
network and enters POWER DOWN mode, and only RTC is still active. POWER DOWN can also
be indicated by VDD_EXT pin, which is a low level voltage in this mode.
3.4.2.4 Emergency shutdown
The module can be shutdown by driving the EMERG_OFF to a low level voltage for over 20ms
and then releasing it. The EMERG_OFF line can be driven by an Open Drain/Collector driver or a
keystroke. The circuit illustrates as the following figures.
