00 - Identify the exact build

Prerequisite: None. Firmware: None. Status: NOT TESTED.

Sequence overview | Exact contacts | 3D assembly

Add and test

Inventory only; no power. Mark every inventory.csv row acquired or not acquired; for missing items keep the proposed part number. Photograph both sides of every module, connector and jumper with readable markings. Identify the protected battery and charger separately. List instruments, calibration dates and available dummy loads.

Acceptance checks

• Confirm the exact configuration, parts and available instruments before powering anything.

Send for review

• inventory.csv
• photos of all module markings and both PCB faces
• instrument list

No component substitutions or unidentified module pin positions. Missing equipment becomes a specific pending test, not an assumed pass.

Continuous regression

Before power: inspect the changed wiring against the contact table and photograph it. After power: remeasure every connected rail at the load, verify no unexpected heat/current, and rerun the last accepted diagnostic. Repeat earlier affected tests whenever a supply, cable, firmware or grounding connection changes. Record failures and repairs; retain the previous accepted evidence.

If the gate fails

Stop acquisition and remove power before changing wiring. Disconnect only the last-added module and restore the last accepted configuration. Repeat its test. If it now fails, check the shared supply/ground and changed connections before replacing components. Never change multiple modules at once to chase a fault.

Results

Fill measurements.csv; retain raw instrument files alongside screenshots. Outcome starts NOT TESTED. Include units, uncertainty, instrument model/settings, source voltage/load, firmware hash and filenames. Mark unmet criteria FAIL; missing evidence PENDING. Submit the whole stage folder, including failures. A completeness check is not engineering approval.

Stage files

• New wires: exact endpoints copied from the existing wiring table; keep earlier accepted wires. Power-isolation and qualification instructions above override connection order within a stage.
• Probe contacts: available exact probe locations. An empty table means use the instrument instructions above.
• Fixture parts: staged discrete fixture components from the existing BOM; this is not a complete procurement list for modules, tools or consumables.
• Measurements and submission metadata.
