Procurement Notes

This component is officially marked as no longer manufactured and obsolete. Verification of availability requires checking distributor surplus or secondary market channels only. Do not expect new production units from Digi International. Confirm RoHS non-compliance status prior to integration into regulated environments. Ensure compatibility with existing legacy infrastructure given the discontinued status. Validate pinout and electrical specifications against original datasheets before procurement.

Selection Notes

Select this module only for legacy system maintenance or specific historical design requirements due to its obsolete status. Evaluate alternative modern RabbitCore modules if new designs are permitted. Consider the limited support lifecycle and potential supply chain constraints associated with discontinued components. Verify that the 44.2MHz speed and memory configuration meet the target application's processing needs without requiring upgrade paths.
