SIM7022-EVB User Guide V1.00 Feature 6: Module power supply reference design The test points of VBAT and GND of the module are shown in the figure below. If the module needs to be powered separately, the resistance of R112 should be removed first, and then the VBAT and GND test points should be externally supplied with power. www.simcom.
SIM7022-EVB User Guide V1.00 Feature 7: Module power supply separately (VBAT GND) ※ Note 1. The power supply range of the module is 2.2~4.2V, and the recommended power supply voltage is 3.3V. When the power supply voltage is lower than 3V, the radio frequency can work and the performance of a single index may not meet the 3GPP standard. 2.2 (U)SIM card Interface SIM7022 does not support hot-swappable function.
