Summary: Great motherboard, just make sure you have a connector for you hotend fan if installing in an ender 3 v2Review and experience:I bought this after I had kinda given up on the printer. Beforehand I had a setup where it was a Ender 3 v2 with a cr touch, dragonfly hotend, raspberry pi 4B (for klipper), orbiter v2, and dragonfly hotend. I got this on a Black Friday deal and decided to install it on my printer. I will admit setup was a bit difficult because I had to redo the configuration files in klipper and get all the driver settings correct but after that I have been tuning it and it works wonderfully. I previously had issues with my orbiter v2 with the old creality 4.2.7 board even though I had tuned the vref on it and got the multimeter out to make sure it was correct. But after switching to this board and putting in the driver settings I haven’t had an issue with it since. The only thing I didn’t like about the board is the way the hotend fan gets plugged in but that just was because I had an ender 3 v2 that didn’t have the connector on the fan already. Other than that I would give it a 11/10 because it was easy to set up, easy to use, and overall improved my printer by leaps and bounds.

This board ultimately does its job well. If you are switching from a stock Ender 3 Pro v1 board to this board, it is a huge leap forward. If you are swapping this out with an SKR mini E3 v2, you will not notice a big difference. But, in any case, it is well worth the 40 dollar price tag.The Pros:Silences your motors, is 32 bit, fits in the stock ender main board housing, is ABL ready, has a built in boot loader, and it gives you more control over your fans.Cons:This board came with some changes and/or revisions that I didn't love so much, which only counts against it a little, because, overall, I love the SKR mini E3 boards.1. They moved some of the plug ins and changed the hook up type. Namely, the hot end fan. It was moved from the screw in slots to a plug in on the board. This apparently gives you more control over the fan's behavior, but it was a bit inconvenient and required some work and research to get everything plugged in correctly.2. The card reader on this is very fragile. I broke my card reader and had to replace the board because I pushed the card in too hard? That was as confusing when it happened as it sounds in writing. Just...be very careful with the card slot.3. So far, the editable version of the firmware for this has been hard to come by, and info on what environment to use has been even harder to find. I was able to find both and change the firmware to suit my needs, but be warned it is not easily obtained...at least not at the time of this writing.Other than those things, this has been a great board and I would still recommend it.

Board works perfectly fine on an Ender 3 and hasn't been giving me any issues. Stepper motors are a lot more silent and had no issues getting it to run Klipper.The TFT35 however, had some kind of design flaw or manufacturing defect that made it such that when attached to the metal display stand of the Ender 3, the edge of the screen would come into contact with the metal which kept sending touch signals. This rendered the screen inoperable until I covered the edges of the screen with tape.Should be noted that the touchscreen mode also doesn't work with klipper, but that one's on me for not checking beforehand.

Installation was little tricky but relatively straightforward definitely need a board diagram for sure as alot of labels have there own names not corresponding to the same names on original ender 3 pro main boardworks well right out of the box, truly is plug and play i did absolutely no firmware changes and its working as if it came from the factory that way i literally wired it up powered it on leveled the bed and started a printTouchscreen has some really nice additions that make life alot easier like bed leveling gecoded points , direct gcode input and screen responds to touch really wellThe USB flash drive port is a much loved feature that i quite enjoymy print quialty is very much improved i can visually see the differenceAnd omg is this thing quiet ! The fans are louder than the printer granted i kinda like the old robotic sounds i found it kinda soothing and cool sounding but that sound is completely gone replaced with only the sound of the hotend fanMy only complaints areThe out of box firmware does not home or default the printer head when you stop a print it has a delay and just stops on top of the print but this can be fixed in the firmware easly by the userThere needs to be a auto home buttion added to the bed leveling menu as well or it just auto homes first before giving acess to the bed leving menu once selectedWireing diagram should come with the unit in the box in paper formAlso some cable management items like a wire loom and a few zip ties would be niceBut all in all its a 10 of 10 for me so far now im just waiting for my bl touch to show up
