ECO-1042: Main Compute PCBA Rev B → Rev C

Read-only

Transition the Main Compute PCBA from Rev B to Rev C to resolve thermal throttling caused by an obsolescence-driven voltage-regulator substitution. The new pinout requires the Compute-to-Drive Wiring Harness to move from Rev 1 to Rev 2 as well.

Closed all four mitigation outcomes: two PCBA cancellations, one accepted PCBA loss and one harness conversion. — 7/29/2026, 8:14:45 PM
