I replaced my stock Da Vinci 1.0a board with a BTT E3 RRF board. I designed this mounting bracket to be able to mount it in place where 4 of the original mother board screws went. I added brass inserts for the holes for the BTT board. The hole pattern should be the same for the Creality boards that fit the Ender 3 or Ender 5, or any of the after market boards that are direct fit.

This is just the mounting bracket for the board. Not a tutorial on changing the board out.
I might put a project up later once I've got everything lined out detailing what I did with my printer. But for now it's just the file for the mount.

The 5 holes that are raised for mounting the BTT board are sized for M3 brass inserts. If you're going to just screw into the mount, you'll need to resize the holes.
