It seems that you have the same board as mine.

Yes, thanks! I've already made note of all those posts, but it will be very helpful for others.
Someone contacted me privately asking about how the GM328 compared to other versions I tried. I'm part way through editing a video and blog post on just that topic, but I thought I'd add a little more here:
That meter is my favorite of the three I've tried. In casual inspection, it seems to correctly identify every component I've tried, where as the others I tried have had trouble with some depending on the orientation.
I also tried the largest screen Fish8840 version, and
this 91Make version. In retrospect, the largest screen is pointless, in my opinion, and the graphics for components are too "heavy," which makes them hard to make sense of, a problem for the diagrams of simple BJTs and even more so small signal MOSFET.
I like the graphics/ui on the 91Make version best of all, but the firmware seems somewhat dated, doesn't have the full feature set enabled, and the hardware isn't hack friendly -- all surface mount, and to make use of, what I assume are the holes for the programming header, will require either pogopins, or detaching the LCD mounted directly to the PCB.
I plan to compile the latest open source firmware and install it on the Fish8840 tester, taking advantage of what Moejoe learned.
