    This is best explanation, but doesn't include the reference to the FET gate resistors from the drivers for stability reasons.https://endless-sphere.com/forums/viewtopic.php?f=...

    KaeptnBalu, there have been several threads elsewhere (endless-sphere) about it being a good idea to add a TVS diode and a Schottky, to help dissipate avalance current. Have you reviewed this and think it's a good idea or necessary for your design? Also the suggestion of adding ~82 Ohm resistors between the FET drivers and the FET gates. Thanks for your work on this!!

    On the other hand : ordering the two boards already separated is less expensive than ordering the panel. ($10 each) The panel pricing quote was $24.

    Hi - anyone can give PC pricing quote from pcbway? They're doubling cost because saying it's a panel order, so $24 instead of $10 normal. That's not including the shipping component.
