(often designated as version 2.2.x) is an 8-bit mainboard powered by the processor. It served as a significant mid-cycle update for high-end Creality machines like the CR-10S, CR-10S Pro V2, and Ender 5 Plus.
A quick way to identify your board is to check the version printed directly on the board's surface.
The Creality V2.2 board—widely mislabeled as the “4.2.2” silkscreen version—is the silent mainboard upgrade for the Ender 3 Pro, Ender 3 V2, and CR-10 series. It replaces the earlier 8‑bit boards with a 32‑bit ARM Cortex‑M3 architecture and TMC2208 (or TMC2225) stepper drivers in standalone mode. This paper provides a reverse‑engineered block diagram, pinout mapping, power distribution, and critical signal paths necessary for custom firmware (Marlin, Klipper), hardware repairs, and expansion modifications.
Note: Upgrading from V2.2 to 4.2.7 requires changing the LCD cable wiring, as detailed in this YouTube video . Conclusion

The Creality V2.2 board is a popular control board used in 3D printing, particularly with Creality's Ender series and other DIY 3D printer builds. This board is an upgrade from earlier versions, offering improved performance, more features, and better reliability. In this post, we'll dive into the details of the Creality V2.2 board diagram, helping you understand its components, functionalities, and how to effectively use it in your 3D printing projects.
If you are designing a Voron, Rat Rig, or high-speed Ender, replace the V2.2 board with a or Manta M8P . However, keep the V2.2 diagram as a reference – many of its pin assignments live on in modern 3D printer boards.
