slp I'm confused. Did the new board work with the motor? Then you changed FETS and the new board works with the motor?

I didn't test the new board with my 5.2V 1.4A/phase motor,
afraid of frying it too, I tested it with a small 24V .32A/phase motor

I haven't change the FETs yet, I just exchange the 2 board
so I could make sure it's not the problem. I tested the FETs,
they seem fine, but not being satisfied with my own test,
I put FETs from the defective board, and put it on the new board,
then I test the new board and it's fine. Now the FETs that was
on the new board was place on the defective board, then
I test it and the result I posted prior to this.

(I was gonna ask someth about the 5804 version,
but first thing first).
