$50.70 for 3 / untested, will update

Motor driver for big robotics; a slightly-improved clone of a Chinese design. Main difference: added option for 20/26 pin header for easier connection. ~40A, 36V max. recommended.
Probably insufficient heatsinking, but that’s what fits the dimensions I have to work with.
Due to large un-tented vias under each IC, this board may prove to be fully hand-solderable (and even hand-reworkable using only a soldering pencil of sufficient wattage, a solder-sucker, and a dental pick/needle.)

More revisions and improvements likely to come. Common system ground; does not use the +5v line input (yet).
