    WE866E4-P Module Hardware User Guide 6.4.1 PCB Design Guidelines The WE866E4-P module provides a 50Ω antenna pad, which is routed to the antenna connector (or the integrated antenna) by means of a transmission line. It is important that the impedance of this line is controlled to 50Ω. The line should be as short as possible with a constant cross section and without abrupt curves.
