SIM5218E Hardware Design Module Power Module will go to Power off mode when the Power_on pin has Normal operation Off mode been pushed low for 2 Seconds. Module sleep Module will automatically go into sleep mode when there is no interrupt input or other operation. In this case, the current consumption of module will be reduced to the minimal level.
SIM5218E Hardware Design mode (without will not work or the SIM card will not be accessible, or RF part and SIM card remove power will be closed all, the serial interface is still accessible. The power consumption supply) in this case is very low. 3.3 Power supply The power supply of SIM5218E is from a single voltage source of VBAT= 3.4V...4.2V.
SIM5218E Hardware Design used for power supply of the module, user should make sure that the peak current of power supply can rise up to 2A. The reference design is putting one big capacitor at the output of the DC/DC or LDO, and another big capacitor beside the 70 pins connector.
