4.3. Electrostatic Discharge
The module is not protected against electrostatics 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 electrostatics discharge characteristics.
