To prevent electrostatic discharge through the RF pin, do not touch any exposed antenna area. If there
is any risk that such exposed antenna area is touched in a non-ESD protected work area, implement
adequate ESD protection measures in the design.
When soldering the module and patch antennas to the RF pin, make sure to use an ESD-safe soldering
iron.
