Procurement Notes

This component is officially classified as obsolete and no longer manufactured by Digi International. Procurement is restricted to existing stock or secondary market sources. Verify part authenticity and condition carefully when sourcing from third-party distributors. Direct availability from the manufacturer is not possible. Ensure compatibility with existing designs before acquiring surplus inventory.

Selection Notes

Engineers should consider this module only for legacy system maintenance or specific historical design requirements. Due to its obsolete status, new product development is discouraged. Evaluate alternative modern embedded modules that offer current support, updated interfaces, and long-term supply chain stability. Migration strategies should account for potential differences in pinout and software ecosystems compared to the Rabbit 3000 architecture.

Part Context

The 101-0520 corresponds to the RabbitCore RCM3200 series, which was designed for compact embedded applications requiring reliable microprocessor performance. This module represents a specific generation of Digi's embedded computing products, utilizing the Rabbit architecture known for deterministic execution. It serves as a complete system-on-module solution, integrating the processor, memory, and necessary interface connectors into a single form factor for easy integration into larger systems.

Replacement Considerations

Direct substitutes include the 20-101-0520 variant. No other official direct replacements are documented. Designers must evaluate functional equivalence and interface compatibility when selecting alternatives.
