The purchasing decision
Use exact controller and ESC revisions and check the manufacturers’ diagrams. Require polarity and continuity checks for custom batches. Label stock by its intended pair rather than a generic connector description.
Keep these records
- Endpoint revisions.
- Approved wiring diagram.
- Batch inspection and labels.
Give each record an owner and a revision or date. If a supplier proposes a different part or test condition, record it as an exception for review before treating the quotation as equivalent.
Turn the review into a sourcing request
Start with the linked component checklist, add the actual platform and part identity, and state quantity, destination and timing. List unresolved requirements explicitly so the first discussion can focus on those gaps.
