Smart Machine Smart Decision 2.4 Footprint Recommendation Figure 4: Footprint recommendation (Unit: mm) SIM7000 _Hardware Design _V1.
Smart Machine Smart Decision 3 Interface Application 3.1 Power Supply Pin 55, pin 56 and pin 57 are VBAT power input. On VBAT pads, the ripple current up to 0.6A typically due to LTE CAT-M1emission burst and up to 2A typically due to GSM/GPRS emission burst (every 4.615ms). It may cause voltage drop. So the power supply for these pads must be able to provide sufficient current up to more than 2A in order to avoid the voltage drop is more than 300mV.
Smart Machine Smart Decision 3.1.1 Power Supply Design Guide Make sure that the voltage on the VBAT pins will never drop below 3.0V, even during a transmit burst, when current consumption may rise up to 2A. If the voltage drops below 3.0V, module will be work abnormally.
Smart Machine Smart Decision The following figure shows the linear regulator reference circuit with 5V input and 3.8V output. Figure 7: Linear regulator reference circuit If there is a big voltage difference between input and output for VBAT power supply, or the efficiency is extremely important, then a switching mode power supply will be preferable. The following figure shows the switching mode power supply reference circuit.
Smart Machine Smart Decision 3.2 3.2.1 Power on/Power off/Reset Function Power on SIM7000 can be powered on by pulling the PWRKEY pin to ground. The PWRKEY pin has been pulled up with a diode to 1.8V internally, so it does not need to be pulled up externally. It is strongly recommended to put a 100nF capacitor and an ESD protection diode close to the PWRKEY pin, as it would strongly enhance the ESD performance of PWRKEY pin. Please refer to the following figure for the recommended reference circuit.

By default, the L101,R101or R102 are 0 Ω resistors, and the C106, C107 are reserved for tuning. The RF test connector is used for the conducted RF performance test, and should be placed as close as to the module’s MAIN_ANT pin.
