Not to scale. Check the numbers molded on the connector before wiring. Pin colors only show each pin's function. They don't reflect the actual wire colors of any included pigtail.

Before you buy

  • All ports share one 0.6 A, 5 V supply with no per-port fuse, so a shorted sensor lead affects the whole module.
