2. System Connector Interface
2.1 Overview
Electrical connections to the module (except the antenna), are made
through the System Connector Interface. The system connector is a
60-pin, standard 0.05in (1.27mm) pitch device.
The system connector allows both board-to-board and board-to-cable
connections to be made. The table below shows two possible mating
connectors for use in your applications. Use the board-board connector
to connect the module directly to a PCB, and the board-cable connector
to connect the module via a cable.
Figure 2.1 below shows the numbering of the connector pins.
A ground connection is provided at the mounting hole next to the RF
connector on the module as shown below. Connect this ground point to
the DGND pins of the module by the shortest, low-impedance path
possible. The purpose of this connection is to allow any ESD picked up
by the antenna to bypass the module’s internal ground path.
