This is an in-depth explanation of all the electrical and signal wiring for the NEJE Laser Engraver full-GRBL upgrade.
Please see the first video (https://youtube.com/watch?v=2rbzI-d-bOA&t=2529s) for details of installing the new board and setting the driver voltage.
All the wiring diagrams and images mentioned in the video are on the main GitHub page: https://github.com/xunker/neje_laser_upgrades

It’s $6 currently, I think I got it on sale. You can probably find it for cheaper on eBay. Remember, though, if you have the choice do NOT use this and use a “Logic Level” MOSFET instead.
Here is a Logic-Level MOSFET you can use instead of the one above: https://mouser.com/ProductDetail/512-FQU13N10LTU
