Hello,

LCDs work on either/or. Both boards have access to LCD 
pins: https://beagleboard.org/Support/bone101 . That page will show you 
every available pinout. 

Seth

P.S. If you are looking to hardware pins to a LCD display or use the Cape 
headers on the Cape, either/or will work too. I know the Seeed BeagleBone 
Green (or BBG wireless) has some functionality that makes it so you have to 
encounter some /boot/uEnv.txt changes (commenting or vice versa) in that 
file.

...

Since you have many peripherals dedicated to the am335x, I am sure you can 
figure out all sorts of stuff to do! Also, there is a config-pin program 
one can use to alter pin modes, e.g. config-pin p9.16 pwm and/or gpio for 
that specific pin. 
I also noticed overlays are just .dts and .dtbo files etched into time on 
the BBB family of boards. You can find more on that 
here: https://github.com/beagleboard/bb.org-overlays/tree/master/src/arm .
