The V2.2 is an 8-bit, Atmega2560-based control board designed for reliability. It is often recognized by its green PCB color and its capability to handle dual extruder systems and dual-Z stepper motors, making it superior for larger, more complex printers compared to basic Ender 3 boards. Key Features ATmega2560 Dual Z-Axis Support: Two ports for Z-stepper motors. Creality V2 2 Board Diagram
Controls the part cooling fan speed via slicer software.
Runs continuously to cool the hotend heatsink (preventing heat creep) and the mainboard enclosure. It is often recognized by its green PCB
