Tech3d did a video recently about it. The bed MOSFET is rated a 65a/32v and the hot-end and fan MOSFETs IIRC are 35a. More robust that I first thought when I looked it over.
TMC2208 uart control and is working with the 1-cable Creality display. Both with no fuss at all.
So far so good. Now I am working on fitting it into the Creality case. Not to bad so far.
I could move the endstop connectors into 3-pin shells, but I just trimmed off one of the locking hooks on the 2-pin shell instead. Eventually will be testing some optical endstops which will need all three pins on the board, and new wiring, so a hack job was faster. I will glue them in with some E3000 or hot glue to limit my frustration from chasing loose connections.
I am cutting the OE standoffs out of the case. That way I can get the SD card slot in the OEM location and I will have to cut the case for the USB-A connector, but I think it's worth the butchery. I'm never going back to the original or any other Creality control board.
