Review on Enhance Your Creality Printer with BIGTREETECH STM32F103RET6 Motherboard Upgrade by Bob Schultz

I used to have BTT SKR MINI E3 V2 boards (STM32F013RCT6 chips). It seemed to turn on correctly at first. I turned off and flashed an updated base build of Marlin 2.0.x from 5 Mar 21, just like my other boards. After a reboot, all I had was a blank LCD screen. Tried using the SD card that came with it, but to no avail. Research shows that this is a fairly common issue with SKR Mini E3 boards. It looks like an issue with the SD card reader on board. They tend to fail, sometimes while flashing, causing freezes. For those who want to upgrade to this board, I hope you have better luck. However, please note that SKR miniboards are NOT compatible with Octoprint. If you use it frequently I would recommend sticking with the Creality 4.2.7 board unless you need the extra stepper motor Z connector.
