SKR mini E3 V1.2 guide - Best budget Ender 3 upgrade?

The SKR mini E3 board has been updated to V1.2, mostly for the better. I’ve been running the V1.0 in my Ender 3 for some time, and consider it the best bang for your buck upgrade you can do for a stock Ender 3. It is cheaper than the silent Creality boards, yet much more capable.

In this video, I go over the changes to the V1.2 and then test a range of features. The only thing I could get working were the Neopixels, but everything else was working or has fixes and resources below. Thanks to my Patrons for contributing so much to this video!
