6.4. Electrostatic Discharge

If the static electricity generated by various ways discharges to the module, the module maybe damaged
to a certain extent. Thus, please take proper ESD countermeasures and handling methods. For example,
wearing anti-static gloves during the development, production, assembly and testing of the module;
adding ESD protective component to the ESD sensitive interfaces and points in the product design of the
module.
