3.5.3.2. Reference Design for Power Supply of GNSS part in All-in-one Solution
In All-in-one solution, the power supply of GNSS part is controlled by the GSM part through the
GNSS_VCC_EN pin. A reference circuit for the GNSS part power supply is given below. Please pay
attention to the electrical characteristics of GNSS_VCC_EN to match LDO’s EN pin. Please refer to
document [1] for details about the AT commands for GNSS control.
