Notes and version constraints
- The official case is relatively closed; the fan cannot fully cool effectively. Do not run high loads for long periods when the case is used.
- Full functionality requires an external 802.3af-compliant power-sourcing device; it is not included.
- Compatibility with other Raspberry Pi models (e.g., 2B, 5) is not stated in the source and must be verified before use.
- If in doubt about voltage/current values or correct connection, submit a ticket to Waveshare support.
