FRC Wiring

caution

Do not use the REV radio power module to power your Limelight. Its output voltage is too high for most Limelights.

caution

If you are using a pre-2025 Limelight or a white/blue button LL3 or LL3G, it is recommended to dedicate a VRM to your Limelight to prevent destruction during battery disconnect events and extreme regenerative braking events. Limelight 4 can survive such events and does not require a VRM

Standard Wiring
POE Wiring

Run two 20AWG-18AWG wires from your Limelight to a slot on your PDP, mini power module, or a Limelight-Only VRM
- (Not Required) Use Weidmuller ferrules for optimal results (Pictured, 20AWG Wire with Weidmuller 20AWG Orange ferrules)

Add any breaker (5A is ideal, but any breaker will work) to the same slot on your PDP.
Run an ethernet cable from your Limelight to your robot radio.
Add strain reliefs to all power and ethernet cables going to your LL.
Use twisted Cat6 cables with stranded wires, ideally 20AWG
