I am pasting a PDF version of my KiCAD schematic to see how it appears on this forum in a post.
MOSFET Power Switch.pdf (33.8 KB)
I am not able to get it enlarged to fit the page better. Since it is such a small schematic it would be nice to see it a little larger
Thanks, @LarryD . I see you did that while I was messing around with my second attempt. What did you do? I Just zoomed in on the schematic until it showed what I wanted and then took a screen shot.
Screen shot here too.
Thanks. Looks like I have this down for future needs.
A schematic sure does expose exactly what’s going on.
Hi,
Check in the Files section of KiCad and see if it has an EXPORT function.
EXPORT as a jpg and it will post directly into a post.
Tom.. 
Fine looks good.
Thanks.. Tom...
Thanks for the suggestions. Some day I will have a complicated schematic and won’t be able to fit it all on a single page.
As a side note it took me 1 - 2 hours to “reverse engineer” that circuit from the circuit board and create a usable hand drawn sketch. And about 4 hours to recreate it while learning KiCAD. But at least I was learning.
This module looks like the same one I bought from Temu. I also ran across a YouTube video showing how to use an identical looking module. Mine cost $4 for 5 of them. I bought 15. The MOSFET’s are D4148 or AOD4148. A very nice looking unit for logic level switching according to the spec sheet.
Are these MOSfet´s are Arduino compatible wrt logic level?
As you can see from your schematic, the MOSFETs are in parallel, that’s some serious power capacity.
Keep in mind this is a Low Side Switch.
A year from now this will only take you 5 minutes to draw up from the PCB. 
They have a threshold of 2 volts fully on at 4.5 volts
I don’t know what the difference is between the “A” suffix and without.
