The Data Port Logics was developed by Michael Erwin.
It’s driven by a Maxim7219 LED driver chip and supports 38 LEDs. Building and design is like the Teeces or CBI.
In theory it would be possible to run Teeces, Data Port Logics and CBI from one Arduino. But it makes more sense to seperate Teeces and DP & CBI because of their position within the Droid.
The biggest obstacle with the DPL are the LED Light Bars.
I found only one source worldwide and that’s Mouser.
