Can I connect a few L293B chips in parrallel, litterally, pin to pin, cause I need a bit more current than one can give me and the board's already done?
There are pointy haired bald people.
Time flies when you have a bad prescaler selected.
I looked at the datasheet and it does look possible. But in my experience if you are looking for serious current requirements or in need of board space then go for a bridge driver that has the nuts to do it all in one package.

Why not L298D? More current, heatsink, popular, but probably expensive.

The board has already been done for a L293. The L293 *SHOULD* suffice, but I'm asking this in case I underestimated the motors.
IIRC, SN754410 is pin compatible with L293, probably cheaper (at least the offers that I had), and, if my memory serves me well, it has some improvements inside that include better protections against underestimated loads.
Neither of my parts distributors have that chip in their catalogs. :-(
For now, the system works OK, no problems so far, I'll see when I apply the full voltage if the bridge explodes :-D
