Page 17: Hardware Design
UM220-INS Series Modules User Manual 5 Hardware Design 5.1 Design in Considerations It’s required to connect the following signals correctly to make UM220-INS series modules work properly. When the module is not powered on, it is necessary to ensure that the power supply and all GPIOs are in a high impedance state or a low level to avoid abnormal operation of the module caused by power leakage. -
Page 18: Power Supply Requirements
5.2 Power Supply Requirements 5.2.1 Main Supply (VCC) The voltage range of VCC is 3.0 V ~ 3.6 V. Notes: The VCC initial level when power-on should be less than 0.4 V. The VCC ramp when power-on should be monotonic, without plateaus. The voltages of undershoot and ringing should be within 5% VCC. -

Page 26: Module Calibration And Notes
5.8.5 Module Calibration and Notes Self-Calibration After the installation of the UM220-INS series modules, the self-calibration is required to ensure the accuracy of the module output. In the process of the self-calibration, the module estimates installation status parameters and sensor parameters. The module is in GNSS navigation mode before the self-calibration is completed, and is in GNSS + INS integrated navigation mode after the self-calibration is completed. -
