electonics schematics...

I've been looking at the schematic for the UCB v1.2.1 which i am using and cross referencing the pin outs with whats given on the stepper controller and extruder controller pages of the website(latest ones) and things are different!

Obviously the boards have common connections and its the PIC chip coding which is different.

On the schmatic, pin 1 goes to step 3 input of the l298n but on the webpage it says pin 12 goes to step 3!?

pin 17 is not used on the webpage but in the schmatic it goes to step 4 input of the l298n!

if anyone could shed any light on this it would be much appreciated!

also what are those connections to the right entitles bread board? is that for testing purposes?
as pin 12 & 13 go to this and on the website they say they go to step 3 and step 4 of the l298n!
