Style: SKR Mini E3 V3.0
This is very good quality. Watch a couple of online videos to see how to install it. It has quite a few ports and connectors, not all of which you will probably use, but almost certainly everything you will need. I am using it with a CR Touch auto bed leveler. My only complain is that one of the temperature sensors needs a JST-XH connector (the Creality board just takes the raw wires). So I had to buy a connector kit, which was a bit of a pain. Outside of that, the installation was easy and went without any other issues. The result was that the printer suddenly became very quiet. I don't know why or how the old board made the stepper motors so noisy or how this board makes them so quiet, but it makes a big difference. It isn't silent, but it sure is better. Outside of the improved sound, it just seems to be a higher-quality board than the OEM board, and it seems to have more options available. I strongly recommend this to anyone who owns an Ender 3 Pro.

Style: SKR Mini E3 V3.0+Bltouch with 80cm Cable
NOTE: I have not installed BL Touch yet, but had to leave a review just because of the world of difference this 32-bit board made for me with leveling. Without knowing what I was doing with my old 8-bit motherboard, I put the temp up too high and destroyed it. I'm glad I did because it gave me a reason to replace it with this amazing thing. The 8-bit board that comes with the printer has no type of leveling help. Used to take me a couple hours to level the printer. Now, with this, it takes minutes. I haven't even installed the BL Touch yet but the digital leveling it can do is way faster, easier and more reliable than manually doing it. Round Edges also come out a lot more smooth.

This mainboard was by far the best upgrade to my Ender 3 Pro (MicroSwiss all-metal hotend is a close second). The TMC 2209 drivers make the steppers so quiet that I sometimes forget it is actually doing something (although there is the fan noise). The added space on the EEPROM was perfect for fitting all the features I wanted into my Marlin build (Linear Advance, Auto-Bed leveling, and Junction Deviation in particular). Not entirely sure why BIGTREETECH only lists 256KB...it is actually 512KB which allows me to compile 'bloaty' stuff (PIDBEDTEMP, M503, boot images, extra menu items for LCD, etc.) into the firmware and not have to worry about saving every last little byte. Installation wasn't difficult, but it was frustrating as Creality hot-glued everything to their stock board. Took a long time to get that stuff off without damaging anything. Came pre-loaded with a recent version of Marlin and was easy to flash to a custom build by simply dropping a 'firmeware.bin' file onto SD card and turning the printer on. A nice feature is that after it updates the firmware, it renames the file to 'firmware.cur' so it does not try to reflash every time you turn the printer on (the bootloader I flashed to my stock board didn't do this). BLTouch & Auto-Bed Leveling I did have some trouble configuring the firmware for ABL using the BLTouch at first. Most guides out there assume you are plugging into the Z-Stop on the board, but this board has the 5-pin header for BLTouch (which was convenient to build a 5-pin DuPont connector right to the board instead of separate 3-pin and 2-pin connectors). In your configuration.h, make sure that #define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN is commented out and that you are using #define USE_PROBE_FOR_Z_HOMING. One other thing I had to change was #define Z_MIN_PROBE_PIN PC14. PC14 is the Z-endstop pin from the 5-pin header. The pin set to this by default will not work. In configuration_adv.h, PROBE_OFFSET_WIZARD is a really handy menu option to help set the z-probe offset value. There are other minor things you have to change to get ABL to work, but all the guides out there cover that in great detail. The Instruction Manual does include a link to pre-compiled Marlin binaries for this board. I believe from that page the 'firmware-bltouch.bin' would have worked for me using the 5-pin Z-Probe header, however the webpage is unclear and I wanted more control over what features were in my firmware. Would be nice if they supplied the configuration.h and configuration_adv.h files for these builds so that users know what's in them. Extra Stuff I bought the kit with the Mainboard, BLTouch and no touchscreen display. Be aware that the wires for the BLTouch probe are nowhere near long enough to reach your mainboard. You WILL have to do custom wiring or need to buy a BLTouch extension cable (1-meter should be long enough). This kit does NOT come with a bracket for the BLTouch either. I printed one out from Thingiverse and it works great, but if you prefer a metal bracket, you'll have to buy it separate from this. The kit does have appropriate screws/washers/springs to install the BLTouch. It is pretty clear in the description and pictures that it would not come with the bracket or long-enough cabling, however some folks might not notice or realize they need these things and be very disappointed. Overall a great board and an awesome upgrade that would really only be better if the documentation was more specific instead of a few pictures and incoherent sentences. In particular, configuring Marlin for BLTouch using this board's 5-pin header (notably the PC14 pin). Oddly, the BIGTREETECH configuration files specifically for this board on GitHub for Marlin do NOT have the pin defined as PC14. Despite a few challenges, this is still 5-stars all around because this upgrade is not designed for people who like for things to 'just work' or simple plug n' play. Go buy a more expensive printer if that is what you want.

I already have a BIGTREETECH SKR Mini 2 so I figured the version 3 would be even better. I am very pleased with the board so far. It's just as silent as version 2. My favorite feature is individual fan control. Fans turn off when the parts cool off. Great if you print while sleeping. The only issue for me is that the cooling fan wire needs to be cut to add the JST connector so that it plugs into the motherboard. The board should come with the JST connector for the price you pay. Taking off 1 star for that. Other than that..... get it!

Had my 4.2.7 board fail, so got another, which had a loose connecter, replaced that, and that one had two loose couplers. So, decided to try this with my E-3 and Node Pro and it works great. Some small tweaks and my custom Marlin build was running well. Have not tried linear advance yet, but will soon. So far, this is a solid board and has ben performing well.

I never realized how noisy my stepper motors were until I installed this board. Definitely a great quality of life improvement. Maybe I’ll upgrade to quieter fans next!

Super easy to install with my ender 3 pro! Used to have glitched out firmware before this and now I don’t have any issues with the UI. Little bit of confusion with using the CRTouch as all the videos out there only show BLTouch but managed to get it working. Downside is that I have to use the Z stop in order for the CRTouch to accurately level the bed. Overall, great upgrade and the only noise complaint comes from the fans.
