Connector loop wiring

Show a link between two pins inside one connector.

Generated directly from the example YAML with WireViz 0.4.1.

Purpose

Use loops to document an internal pin-to-pin link separately from the external cable. This jumper arrangement is illustrative, not a certified electrical design.

Components

JUMPERED has four positions and an internal link between pins 1 and 2.
DEVICE has two positions.
W1 contains two 24 AWG conductors and is 0.3 meters long.

Wiring

The declaration loops: [[1, 2]] connects pins 1 and 2 within JUMPERED. Its pins 1 and 3 connect through the cable to device pins 1 and 2. Pin 4 is unused. A loop does not create another cable conductor or automatically add a separately purchased jumper to the BOM.

What to change

Each loop entry must contain two existing pin IDs. Add further pairs for other internal links. If a real jumper needs its own procurement entry, add an additional BOM item with the appropriate part and quantity.
