What X-Cards are Available for the GX400/440/450?

The GX400/440/450 devices have an expansion card slot which greatly increases the versatility of the platform.

As of August 2012, Sierra Wireless has provided a WiFi X-Card that enables a WiFi (802.11 b/g/n) hotspot (access point) and supports WiFi client mode.

Since late 2012/early 2013, Sierra Wireless has made available two additional X-Cards to support extra Ethernet Ports and expanded I/O (inputs and outputs).
