Quote from: pito on May 18, 2013, 11:59 pmShow us the schematics..Nature path. I chatted with one of my friend at Shenzhen this weekend and show the image of this motor driver.Here is what he told me;-The driver is overly popular in industry lately, there are a little of hundreds if not thousands manufacture to produce it.among them, there are a lot of two persons operation; - one for sales, one for design clone and QA. It is much like Apple Computer in 1976. "The original Apple Computer, also known retroactively as the Apple I, or Apple-1, is a personal computer released by the Apple Computer Company (now Apple Inc.) in 1976. They were designed and hand-built by Steve Wozniak. Wozniak's friend Steve Jobs is only salesman during that time." and all the part for build will be easily to obtain in days if not hours at local. The physical build is take place here;-He told me the schematics is not available to his company even they are using a lot of them. if you look it carefully IC name is erasedby sandblasting or sand paper. He indicated all three power mosfet name name is erased as well. of course if I need schematics he could get it for me, but I told him no, not until I start same manufacture business....
Show us the schematics..
