Old thread I know, but thought I'd give a bit of feedback - I bought this board a couple of years ago when I was clueless...Is still am, but I can report that I've fried about FIVE A3977 ICs during the time I've owned it. Two of these were probably down to my fault (bare pcb base touched something metallic etc)...but he other three...hmm.
Of course swapping out the A3977 on this board is a breeze since they're socketed, but at $10 a pop (delivered) having these ICs fry so frequently is wearing a bit thin.
My only other board to gauge this one against is a cheap Chinese TB6560 variant.....that chinese one is awful and makes the mechatronics one appear ooze quality by comparison! |
