EPM-DK02 Module: 2 mini PCIe Sockets

The EPM-DK02 has two mini PCIe sockets that may be used for cellular communications expansion. The figures

below show the slots’ specific locations. Note that while both sockets provide a mini PCIe interface, socket one

supports either mini PCIe or USB 2.0 signals, whereas socket two only supports USB 2.0 signals.

Connect the cellular module to the mini PCIe socket, and insert the SIM card into the SIM card holder. Be sure

to tighten the screw in the screw holder so that the module will be firmly installed. Note that the second SIM

card holder is located on the back of the module. If you need to connect antennas, use the connectors on the

side panel.

Installing Cellular/Wi-Fi Modules on the

EPM-DK02/EPM-DK03

The EPM-DK02/03 has two mini PCIe sockets that allow users to insert two mini PCIe cards for cellular or Wi-Fi

communication. Note that while both sockets provide a mini PCIe interface, socket 1 supports either mini PCIe

or USB 2.0 signals, whereas socket 2 only supports USB 2.0 signals.

Users may purchase the cellular and Wi-Fi modules for the EPM-DK02/03 separately. The instructions for

installing the cellular and Wi-Fi modules are specified in the following sections. To make it more convenient to

install the antenna, install the module at Socket 2 first.

Configuring Power Controls on Socket 1

To use socket 1 as a USB interface, the user must allow the platform’s

general-purpose input/output (GPIO) to control the power; in contrast, for the

PCIe interface the power must be constantly on. These power controls must first

be set at the hardware level, using the jumper shown in the figure at right.

1. To enable GPIO control of power for a USB interface, place the jumper on

pins 1 and 2.

2. To disable power controls for an always-on PCIe interface, place the jumper on pins 2 and 3.

NOTE

This jumper configuration is for socket 1 only.
