You can pack a lot of crap into an 8 x 11 area with a little playing around.
I may get everything else I wanted in and two copies of the motor controller,
for 20 total not just 10.
Fit in 9 per panel of just the controller and that would be 90 total for
$220/10 panels for double sided, only $2.50 per board. Shave just 1/3" off the
width and 1/4" off the length and you could do 12 per panel for under $2 per
board. Likely not easy to do in width with the 3 wide drivers, but taking off
the outer gate traces and just using 2 jumpers for the rare times most need 5
phase would probably make it work.
Twenty of these will still let me keep 10 of my large and 50 of the small of
the main board I want, with room left over for 10 PIC programmers and maybe a
copy or two of just the MOSFET driver area, for easy driver tie in to other
boards. Sounds like a plan to me.
May sell some off at cost to not be making money off them from Eagle. Might
up things a bit on the parts (consider it a parts storage fee lol, they've been
around a while..). They'll still be dirt cheap at 5 times what I paid, I hunt
the bargains and get them for next to nothing.
Also aiming for a TSOP pattern within a PLCC pattern for the PIC if possible,
so either can be used. May not work though, or take modifying the pads. Ah,
the patterns fit barely. May not solder as easily if I have to modify the pads
for clearance, but I'll make it work somehow.
I love making my own boards for testing prototypes, but getting so many of
several made boards back for only 2-3 weeks and only a few bucks each will beat
the pants off of actually trying to make anything like these in quantity.
