The CSL is a full digital addon board for the bodylights.
It can run stand alone via the rear mounted Arduino or as slave board via the D-DPL.
You can also run the leds via another Arduino via the digital in pin.
Also available are the serial command pins.
The CSL+ is much more powerful board because it can control other Bodylights or anything else you have in your droid (if you make your own code for it) via the 6 buttons each coinslot is used for.
It has pinout for several pins (in/out), serial command pins and a buzzer (Simon says).
I2C is possible if you use the arduino pins direct.
