1. Prepare

Verify component pinouts against each manufacturer’s datasheet before wiring. Label cut wires with their wire numbers; the same numbers follow them through every stage. Wire colors are written out for black-and-white printing. Custom colors can be named in the wire library.

Progress is saved on this browser for this board revision. Changes to the board or measurements start a new checklist. Printed diagrams are references, not life-size templates.

8 wires to prepare; 190mm total wire, including end allowances.

2. Cut wires

8 wires · +5mm per end for lead-through

Total wire: 190mm (7.5in)

3. Bend wires

Use the straight-line ruler to mark bend points on the wire before bending. Use the bent shape as a visual reference while bending.

Wire 1 — DARL — G14 → H15 — 14mm — Red

Cut 14mm.

Wire 2 — SWITCH — G16 → F23 — 30mm — Yellow

Cut 30mm. Bend 90° left at 23mm.

Wire 3 — SWITCH — E24 → H24 — 18mm — White

Cut 18mm.

Wire 4 — SENSE — F12 → E15 — 20mm — Green

Cut 20mm. Bend 90° down at 8mm.

Wire 5 — SENSE — I10 → I6 — 20mm — Blue

Cut 20mm.

Wire 6 — VCC — D7 → D17 — 35mm — Black

Cut 35mm.

Wire 7 — GND — D5 → K5 — 28mm — Red

Cut 28mm.

Wire 8 — GND — K7 → J12 — 25mm — Yellow

Cut 25mm. Bend 90° left at 18mm.

4. Place wires

Component side. Select a wire to emphasize its route in its own color and highlight its endpoints. Wires follow number order, matching the bend guide and solder checklist.

5. Solder connections

Bottom view: horizontally mirrored. Coordinate names still identify the same physical holes. Highlights mark wire endpoints; wire routes belong on the component side. Check each connection and the listed solder bridges.

Board is horizontally mirrored. Column A is on the right.
