Grounding metal covers
Attempts to improve grounding by soldering ground cables, wick or other forms of metal strips directly onto the
EMI covers is done at the customer’s own risk. The numerous ground pins should be sufficient to provide
optimum immunity to interferences and noise.
u-blox makes no warranty for damages to the NEO-M8P module caused by soldering metal cables or any
other forms of metal strips directly onto the EMI covers.
Use of ultrasonic processes
Some components on the NEO-M8P module are sensitive to Ultrasonic Waves. Use of any Ultrasonic Processes
(cleaning, welding etc.) may cause damage to the GNSS Receiver.
u-blox offers no warranty against damages to the NEO-M8P module caused by any Ultrasonic Processes.

EOS/ESD/EMI precautions
When integrating GNSS positioning modules into wireless systems, careful consideration must be given to
electromagnetic and voltage susceptibility issues. Wireless systems include components that can produce Electrical
Overstress (EOS) and Electro-Magnetic Interference (EMI). CMOS devices are more sensitive to such influences
because their failure mechanism is defined by the applied voltage, whereas bipolar semiconductors are more
susceptible to thermal overstress. The following design guidelines are provided to help in designing robust yet cost
effective solutions.
To avoid overstress damage during production or in the field it is essential to observe strict
EOS/ESD/EMI handling and protection measures.
To prevent overstress damage at the RF_IN of your receiver, never exceed the maximum input
power (see the
NEO-M8P Data Sheet
[1]).
Electrostatic discharge (ESD)
Electrostatic discharge (ESD) is the sudden and momentary electric current that flows between
two objects at different electrical potentials caused by direct contact or induced by an
electrostatic field. The term is usually used in the electronics and other industries to describe
momentary unwanted currents that may cause damage to electronic equipment.
ESD handling precautions
ESD prevention is based on establishing an Electrostatic Protective Area (EPA). The EPA can be a small work station
or a large manufacturing area. The main principle of an EPA is that there are no highly charged materials near ESD
sensitive electronics, all conductive materials are grounded, workers are grounded, and charge build-up on ESD
