Electrostatic Discharge - Quectel EC21 Series Hardware Design

6.7. Electrostatic Discharge

The module is not protected against electrostatic discharge (ESD) in general. Consequently, it is subject
to ESD handling precautions that typically apply to ESD sensitive components. Proper ESD handling and
packaging procedures must be applied throughout the processing, handling and operation of any
application that incorporates the module.
The following table shows the module's electrostatic discharge characteristics.
