# LED patterns

This page contains an overview of the meaning of the LEDs on the boards. We make a distinction between anchors and tags.

Note

Not all boards have the same amount of visible LEDs. The green and red led are always available on all boards. Some boards have some extra LEDs. For full reference, check our hardware page.
