Procurement Notes
Verify the specific suffix 'C-25' against official documentation to confirm regional regulatory approvals or pin header configurations. Confirm that the required development environment aligns with the NET+OS platform or plug-and-play firmware requirements specified in the datasheet.
Selection Notes
Select this model for applications requiring reliable wired Ethernet connectivity within an extended temperature range (-40°C to +85°C). Ensure the design accommodates the 12-pin form factor and utilizes the provided JTAG interface if hardware debugging is necessary during development.
Part Context
This part belongs to the Digi Connect EM family, which shares a common platform design with the wireless Digi Connect Wi-EM modules. Both families utilize the same 32-bit NET+ARM processor technology, allowing for interchangeable use in product designs based on connectivity needs.
Replacement Considerations
The Digi Connect Wi-EM series serves as a functional alternative for wireless connectivity while maintaining pin compatibility. For direct replacements, verify availability of other suffixes within the DC-EM-02T series that match specific regulatory or connector requirements.
