BigTreeTech SKR MINI E3 v2.0 32 Bit Control Board Integrated TMC2209 UART In stock

Can’t say enough about this board! Really like it. I have loaded Marlin 2.0.7.2 along with BLTouch and a BTT smart runout (aka jam) sensor, and a working neopixel. Very happy with it. Enabled every Marlin feature I could think of and it has plenty of room to spare. Paired it with my new BTT TFT35 E3 and it’s perfect! Go ahead get them both you won’t regret it.

Best money I’ve spent on any upgrade for my ender 3. The steppers are silent, the 32-bit board and expanded memory have allowed me to use so many more settings on my printer. It’s opened up my options for experimenting and refining the Marlin firmware, but also just worked great out of the box. Along with upgrading the springs and getting an all metal extruder, this an essential upgrade in my mind. Definitely if you have an 8-bit board, it’s a must buy.

Must have upgrade

Replaced dead board in Ender 3 V2. Board works without issue but be warned that it technically only has 256kb of memory. Lots of people online are compiling the 512kb firmware packages on these chips but that's extremely dangerous and can cause lockups and other unexpected behavior. The chip is a stm32f103rct6 which according to the manufactures datasheet has 256kb of memory. Big Tree Tech themselves provide firmware packages with 512kb so watch out.

After looking at several YouTube reviews, I installed the SKR MINI E3 V2.0 control board on an unmodified Creality Ender 3 Pro. The install went very smoothly and took about 10 times longer than the YouTube demonstrated installs as I checked everything 2 or 3 times. (It took me about 3 hours.) I labelled every wire before installing, checked again and powered up the Ender 3. I then installed the MARLIN V2.0 for the SKR MINI, using the GITHUB site and following directions. I tested the board using CURA 4.6 with an Ender 3 profile and printed the "xyz" 20mm cube with great results. The machine was absolutely silent. I used the existing LCD display rather than the SKR display.

Using this board in an Ender-3 or a CR-10 makes a great difference. When printing, mostly you hear only the fans. Installing this board is not complicated.
