3.3.2 Power Supply 3.3V Interface
When the ME936 module works normally, power is supplied through the 3.3V pins
and the voltage ranges from 3.135 V to 4.4 V (typical value is 3.3 V). The ME936
provides 5 power pins, and 11 Ground pins. To ensure that the ME936 module works
normally, all these pins must be connected. The M.2 connector pin is defined to
support 500 mA/Pin continuously.
When the ME936 module works at GSM mode, the module transmits at the
maximum power, the transient peak current may reach 2.5A(with a highly

unmatched antenna). In this case, the power pin voltage will drop. Make sure that the
voltage does not drop below 3.135 V in any case.
The traces of the power supply should be as short and wide as possible. It is
recommended that at least a 220 µF capacitance is added onto the 3.3 V power rails
and as close to the M.2 connector as possible. Customer can reduce the capacitance
if it can be guaranteed that 3.3V pin does not drop below 3.135 V in any case.
Figure 3-2 shows the recommended power circuit of the ME936 module.

3.3V pin must never be under 3.135 V during the 2G transmitting burst, as shown in Figure 3-

If customer wants to power cycle ME936, the 3.3V pin must stay below 1.8 V for
more than 100 ms. The sequence is shown as in Figure 3-4 .
