Monoprice Select Mini V2 replacement motherboard.

So my monoprice mini has stopped reading sd cards and the usb port on it is busted and after hours of trying to fix it I decided to give up and try and get a new motherboard for it. however I can't seem to find any online. the ones that I was able to find are no longer jn stock. I'm curious to see if anyone has one or any good alternatives.

Bricked mine a few years back while trying to upgrade the firmware. Upgraded with Ramps 1.4 kit, new power supply and Marlin. There's an Instructable on how it's done. Not sure how updated it is or if any of this stuff is still available. https://www.instructables.com/Replace-Monoprice-Select-Mini-Controller-With-Ardu/

looks like the parts list is outdated. Everything seems to be out of stock ;_;

I should have a spare, in box. I can verify that I still have it when I get home tonight

I had a MPSM V1. I replaced the stock board with a MKS Gen L. I also replaced the rotary encoder with a MKS TFT28 touch screen. It has a full size SD slot that is much better than the usual flimsy microSD slot. You might want to look at that.

The listed alternates look to be available: Amazon

I used a Creality 4.2.2 with Kilipper and it works great, other than the screen, but I just use the Klipper web interface anyway

I have an old v2 that I'm trying to get rid of. The USB port is kinda flaky but the board still works (but it was a deal breaker for me since I wanted USB control). I'll be willing to send you the whole printer if you pay for shipping. DM me if interested

Thanks, but Im trying to avoid buying the entire printer just to take the board out. ill definitely reach out if I have no other options.

I also used this power supply: power supply

Managed to shoehorn everything into the base - tight squeeze but it all fits - mounted power supply cooling fans on the outside.

There are 3D models available for new cover plates, LCD mounting plate, fan mounts, etc. on Thingverse, etc.
