Electrical compatibility
Review supply and logic levels, connector pinouts, grounding, loads and startup order. A shared protocol name does not establish electrical compatibility.
Engineering decisions
Integration design
Electrical and software interfaces, designed together.
Establish power, signal, data and control requirements before connecting the system's components.
System architecture and interface definitions
- Power and signals
- Data definitions
- Control responsibilities
Compatibility across hardware and software
A component can operate correctly on its own yet be incompatible with the surrounding system. Integration design examines electrical limits, data interpretation and command timing together, giving board, firmware and application development a common specification.
Data interpretation
Agree units, coordinate systems, validity flags and timing. Distinguish new measurements, retained state and placeholders before using a value elsewhere in the system.
Control responsibility
Assign command authorisation, state storage and interruption response. Specify which component stops an output, rather than leaving two components to assume the other handles it.
Engineering process

process.
- 01
Map the system
Show the components and the power, signal and data paths between them. Identify each component's role.
- 02
Document interfaces
Specify relevant pinouts, message structures, update rates and exceptional states for each connection.
- 03
Connect a complete signal path
Link one real input to an observable output through the system. Use this limited implementation to identify incompatible assumptions.
- 04
Add and verify functions
Integrate the remaining functions against the same specifications. Check relevant startup, invalid-data and interruption cases.

- Recorded checks, observations and open dependencies
The assignment must identify the systems and access available. Interface review does not imply safety assessment, regulatory compliance or third-party platform guarantees.
