IRIS OEM Edition Hardware Reference Manual3 Product OverviewCrossbow’s M2110 OEM Edition module provides users with high level functional integrationdesigned to optimize the addition of wireless mesh networking technology to a wide variety ofboth new and existing custom sensing applications. Powerful new design features include:• Optimized processor/radio module integration based on Crossbow’s extensive Motedevelopment and deployment.• Flexible onboard hardware interface for both standard and custom sensing devices.• Comprehensive software support, including sensor board drivers and algorithms, viaCrossbow’s industry leading MoteWorks software platform.The M2110 OEM Edition module is the functional equivalent of Crossbow’s newest generationIRIS family Mote in a postage stamp form factor. This inherent design continuity makes theOEM Edition module an ideal solution for next-generation mesh networking products anddesigns.By utilizing open-platform, standards based interfaces the OEM Edition module offers users anattractive value proposition consisting of easily differentiated, low-power radio/processormodules that can be rapidly designed and built.Figure 3-1.
