Graphic LCDs / Re: NHD-C12832A1Z-FS(RGB)-FBW-3V Backlight Color Control

Ok, Thanks.
Now I have  a question about voltage levels:
1. If I use a 3.3V supply, does the interface board provide regulated voltage levels? (i.e. 3.0V for VDD and the green and blue backlights, and 2.1V for the red backlight)
2. Where can I find a schematic of the interface board?

Can I connect the K(R), KG), and K(B) pins directly to the GPIO lines of my MPU to control the backlight color, or do I need current limit resistors and a driver to sink the backlight current?
What about when using the NHD-PCB12832A1Zrev2 interface board?
