Pre-Certied Module Pin Assignments
The pre-certified version of the module has mostly the same pin
assignments as the standard version. The antenna connection is routed to
either a castellation (-CAS) or a u.FL connector (-UFL), depending on the
part number ordered.
The antenna pad is disconnected on the version with the connector. The
RF is routed as shown in Figure 16 for the version without the connector.
