@mihun70Overall it looks pretty good and without more details and schematics it's hard to know exactly what does what, but I have the following commentsIs this single layer? If so you've done well.What are the MOT headers for? The headers don't appear to be aligned, for example DIG1 and PWM. While that has no effect electrically it's just bad form.I don't see any good-sized power and ground traces. The ground traces I can identify are weedy little thing that run all over the board.Most of the "ground plane" doesn't appear to be connected to anything.EDIT:The board doesn't need to be that large as there is a lot of blank space on the left and right sides. Is there a particular reason for that size?There are no mounting holes.As mentioned by us both I think the power rails are the biggest problem here, in fact I can't see where GND get to the chips unless it's through that component just above the "re" in "Core". That component appear to be a resistor which is unusual unless your measuring the current. Schematics would help.______Rob
The Mot are for 2 brushless motors..
Parts of gnd are not to consume too much chloride or cutter fairy on CNC
before to make modifications to the board i remove the power plane...and put again
i don't have place neear the cpus.
QuoteHere's one done, it took 20 seconds, Ok maybe a minute.Good place! i see that you have altium skils...can you help me with 4 holes?I tryed to put them with the mouse but never milimetricaly... i don't know an option like in autocad...if you help me with this...please 10 mm from left and from right and 8.5 mm from up and from down(don't know to tell right in english )

or is my job to redo the work?
