CM3-M2M - Preview

With its rich set of communication interfaces the CM3-M2M board can be used in a wide range of applications where is requested a versatile integration between LAN and WAN technologies.

Two PCI express holders are available to install WAN interfaces like:

• Modems for GSM/GPRS/EDGE/WCDMA/HSDPA/HSUPA/HSPA+ networks like the Huawey HSPA- MU709u
• Lora modules like the nfuse LoRaWAN concentrator
• SigFox modules like the Atim SigFox ACW-MPCI card

On the main board is present the hardware for LAN interface like:

• 2 Ethernet 10/100 ports
• 2 opto-isolated RS485 ports
• 1 WiFi module @2.5/5 GHz
• 1 ISM 868 MHz Yarm radio module
• 1 Internal USB 2.0 port for Z-wave radio modules
