Limelight 3A is a plug and play, zero-code perception system for FIRST Tech Challenge Teams. Based on the battle-tested Limelight 3 for FRC, it brings high performance AprilTag tracking, game piece tracking, and full-field robot localization to teams of all experience levels.
*The REV Control Hub can only support a single LL3A at this time.*
