Wiring

Limelight takes a 12V input, but is built to function down to 4.5V. Its LEDs have a constant brightness down to 7V.

Warning

Do not use the REV radio power module to power your Limelight

Standard Wiring
Power-over-Ethernet (PoE) Wiring
  • Do not run wires to your VRM.
  • Run two wires from your limelight to a slot on your PDP (NOT your VRM).
  • Add any breaker (5A, 10A, 20A, etc.) to the same slot on your PDP.
  • Run an ethernet cable from your Limelight to your robot radio.

PoE allows you to add both power and network connectivity to your Limelight via an Ethernet cable.

Warning

This is not standard IEEE 802.3 (44V-48V) PoE - this is why you must use a passive injector with 12V.

  • (LIMELIGHT 1 ONLY) Ensure that your Limelight’s power jumper is set to the “E” position.
  • Connect a passive Passive PoE Injector to your PDP (NOT your VRM).
  • Add any breaker (5A, 10A, 20A, etc.) to the same slot on your PDP.
  • Run an ethernet cable from your Limelight to your passive POE injector.
