⚫ If the voltage is lower than threshold, the module might fail to start. If the voltage is higher than
threshold or there is a voltage burst during the startup, the module might be damaged permanently.
⚫ If you use LDO or DC-DC to supply power for the module, ensure that it outputs at least 2 A current.
When the module works at maximum power in GSM mode, the peak current might reach 2A. Add a
large capacitor to the VBAT pin to enhance the capability to output continuous current and avoid
voltage drop.
