Creality 32 bit V4 board guide - Ender 3 V2, BLtouch & more

Creality now has 32 bit mainboards, but there is a lot of confusion about which printers they come on and how to compile and flash firmware on them. This video aims to answer all of the questions, covering differences, firmware, BLtouch and filament runout sensing.

Thanks to Leon at Creality for answering my questions, and to the Marlin devs and community for already supporting the new V4.2.x boards.
