The physical dimensions are 1.800 inches in length and 1.550 inches in width, equivalent to 45.80mm by 39.40mm. The operating temperature range spans from -40°C to 85°C.

Feature Summary

• Integrates ARM Cortex-M3 core for embedded processing
• Provides combined internal and external memory resources
• Supports .NET Micro Framework implementation

Applications

• Embedded system development
• Industrial control modules
• IoT device prototyping

Procurement Notes

Verify the specific revision level and manufacturing date code upon receipt to ensure compatibility with existing firmware environments. Confirm that the pinout configuration matches the target carrier board design, as mechanical tolerances must align with the specified 45.80mm by 39.40mm footprint requirements for proper integration.

Selection Notes

Select this module when a compact form factor is required alongside significant external memory capacity for complex applications. The inclusion of both internal and external storage allows for flexible data handling strategies. Ensure the application environment remains within the specified -40°C to 85°C operational temperature range for reliable performance.

Part Context

This component belongs to the GHI Electronics G120 System-on-Module family, designed for drop-in replacement scenarios. It serves as a complete computing solution integrating the processor, memory, and necessary support circuitry into a single small module, facilitating rapid deployment in space-constrained electronic designs.

Replacement Considerations

Cross-reference with other G120 series variants such as G120B-SM-373 for alternative memory configurations or interface options. Verify mechanical compatibility before substitution, as different suffixes may indicate variations in package type or memory size that affect direct interchangeability.
