Figure 9 U.F.L Connector Size
ESD design 2.6
ESD grade of module: Human Body Model (HBM) sensitivity is 2000V, Charged Device Model (CDM) sensitivity
is 500V. If a higher ESD level is required, the pins that may be connected to the outside should be reserved place for
the ESD protection device.
If the module connects the mother board by outside leads, application designers should notice the EMI problems.
Using shield cable or reserving the position for common mode choke to solve this problem.
