P2B8 with green LEDs
This is the same as the normal DROID P2B8 controller just with green LEDs in the buttons instead of white ones.
The P2B8 controller provides 2 potentiometers and 8 push buttons for free assignment to any of the DROID's parameters. You can attach up to 16 controllers to one DROID master.
The P2B8 controllers are daisy-chained from the DROID Master and then to each other. The controllers receive power from the DROID Master, so they add to the power consumption of the DROID Master. The controller does not consume a power connection on your system.
Additional to the shipped cable, there are longer cables available:
