That’s my assumption. As long as you sell steppers spec’d such that the system will be unhappy at 2A, I’d avoid this like the plague.
On a system that can get covered in dust or put in a box? Don’t count on it.
Well the three most recent steppers I have sold (covers 7 years or so), 1.5A, 1.7A and 2A…so 120, 110, or 100mohm?? Feels like 110 is safe. ~1.80A RMS seems like plenty even for the 2A stepper?
Sucks cuz I just put in 100m in to easyeda.
Bummer, that is a sizable cost savings.

Yes, using a FET that way to prevent blowing up the board with reverse voltage is REALLY smart.
Best part, when that FET is on, it’s a very low loss, far better in my opinion than the old diode bridge way of doing this.

I could use a second set of eyes. I see a discrepancy in my esp32 vs Barts’s Corgi.
The issues circled in yellow, And the logic chart is included.
Here is Bart’s.
And from espressif direct.

It was a confirmed mistake.
I quite like pluggable headers, as you can connect the wires to the plug (generally a screw terminal) and then plug into the header on the board.
These are potentially good for power as they are mains rated, but there are quite a few variants of these on the market.

The issue with pluggable headers is I have to buy them separate. I can not find a way to get jlc to make the board and add the plugs, so that is another inventory item, another shipping charge, and another thing to assemble.
They don’t have a concept of DNI (Do not Install) when kitting for assembly? That isn’t terribly uncommon for board contract manufacture (at least for commercial board assembly)
