wireless modules

The C90 are 0Ω resistors, and the C6, C9 are reserved for tuning and have no

components. The RF test connector is used for the conducted RF performance test,

and should be placed as close as to the module’s MAIN_ANT pin. The traces impedance

between WSD377 and antenna must be controlled in 50Ω.
