Does the ST67W611M1  (-B version) with PCB antenna have a built in rf switch? We want to programmatically or via pins switch between the PCB antenna and an external antenna.

Hi @Nkh 

There is no internal switch in the module. The connector on the B version already includes a switch; however, this connector is intended for conducted RF measurements, not for connecting a second antenna.

The P version is designed for use with two antennas.
