Official Creality 3D Ender 3 Pro Silent Motherboard V4.2.7 Upgrade Mute Mainboard with TMC2225 Driver for Ender 3/Ender 3 V2/Ender 3 Pro/Ender 5

Best thing is its so much quieter than the original 8-bit board. Quick easy upgrade for my Ender 3 Pro. Upgraded from a 2019 8-bit mainboard. Initially used the firmware provided by Creality. Not a fan of the non-standard messages it sends to octoprint, but worked completely fine. Due to this having a flashable bootloader installed, I ended up trying Klipper. Its all in with Klipper and this board now, works great. There are configuration files for the ender3 pro and its just copy paste to get you setup. From there you can endlessly change parameters to get better prints.

The firmware in the board is 2 years out of date and the thermal run away protection value is set to tight so you get errors before the print can even start. I’m giving it 1 star because you’ll have to compile your own firmware from the current marlin build. Which not everyone knows how to or is comfortable doing, also the fuse was already popped and I got to breath in some nice toxic smoke before I realized what happened and had to replace it with my own. For the average/ casual user this is a bad upgrade and should be avoided

Installed but still can’t get the machine to recognize it to work

Much quieter than the original Ender 3 board. I did need to flash the firmware so there was soom effort involved, but that kinda goes with the territory... fun evening project :)

I knew this board was going to help with stepper noise, but the decibel level drop is shocking! The only thing I hear while printing is the cooling fans, which I dont mind. The other thing I can hear now with it being so quiet, is my prints failing. You can hear bed adhesion failure from a room away, which saves on filament.

Perfect fit, works great, connector for the CRTouch worked. Only issue was I had to reflash it for the printer to home even though it was supposed to be set up for the ender 3 pro by default. The reflash was quick and easy though.

Best update so far from Creality for your Ender 3 Pro! This will eliminate the stepper motor noise! Its absolutely great! If you are running a stock printer, you will be left with just hearing your fans.

Even i was impressed how quiet it made the printer. it also supports his new CR touch

Stepper motors are totally silent now. Print quality is still fantastic. Only trouble I had was flashing the new firmware for my ender 5. But once I got that sorted, its been smooth printing.

My Ender 3 Pro came with a 4.2.2 board, this was a silent 4.2.7 board. I purchased this to help reduce the motor noise. I am floored at how quiet it is. The motors cannot be heard over the fans at all. Only at full speed from one side to the other, I can hear the XY-belts making noise. Installation does require some care, but take your time and get photos first. Highly recommended.
