Schematics infos!

Hi,
I am trying to build a DLP printer with a RPi 2. I just came across the schematics and I cant identify what is the Max232 for.
Is it to be able to turn off the projector?
Also I tough that the PWM of the raspberry Pi could only be achieved with Pin 12-GPIO18 am I wrong?
Thanks a lot!

Rastati,

You are right about MAX232, it is optional and personally I prefer separate usb serial adaptor.
No, it is possible to use any general purpose gpio to send PWM

The nanoDLP schematic and PCB board design is not very clear for me.
There are some errors on PBC design and possible on schematic too; some connections are... "open".

It is possible to have a clear design that helps to better understand how to connect directly or indirectly?
It might help a unitary schematic from GPiO to motor steppers and power, even if is done by hand...

Thanks,

You are right routing software messed up export.
I will update exports on the website in couple of minutes.

Connect two black dots and red dots with wire.

Any update?
It your schematic works?

I would like to understand how to connect, and why is only one contact limit (it is limiting up, or down?):
