BIGTREETECH Upgrade SKR Mini E3 V2.0 Control Board 32bit for Ender 3 Motherboard Silent Board with TMC2209 UART Stepper Driver 3D Printer Parts for Creality Ender3 (with BLTouch Extension Cable)

Very easy to install fit with no problems. Allowed me to update an older Ender 3 Pro with a BL touch. The hardest part was compiling my own software in Marlin. And that was very manageable with some YouTube guidance.

First, the board is amazing. My CR-10 is now so quiet that I initially thought I forgot to connect the motors when I selected Auto Home and didn't hear the stepper motors screaming! This thing is jaw-droppingly silent.However, the total experience is not all great.Unlike other bundles, the bracket for the BLTouch is not included. I had to purchase from another seller for an additional cost.The BLTouch extension cable that I PAID EXTRA FOR is too short, so now I have to make one myself anyway.The instructions are also barely adequate, especially for supposed-CR-10 compatibility. Unlike the Ender 3, there's no precompiled firmware available for the CR-10. I spent HOURS diagnosing a heatbed issue with my original CR-10 (needed to reverse wiring).Overall, probably worth the effort and the hassle, but in hindsight, I should have just ordered the board, purchased a BLTouch kit separately, and made my own extension cable.
