Board Diagram — Creality V2 2

The official diagram shows the 5-pin probe port but swaps the order of GND and VCC compared to standard sensors. Many users have fried their probes because the diagram lacks a clear warning. Community diagrams correct this.

If you own a Creality Ender 3 V2, Ender 3 Pro, or CR-6 SE, you have likely encountered the cryptic alphanumeric code "V2.2" printed on your mainboard. For the maker community, the Creality V2.2 board diagram is more than just a technical drawing—it is the Rosetta Stone for 3D printing upgrades, silent stepper drivers, firmware compilation, and wiring diagnostics.

In this deep-dive guide, we will dissect the official Creality V2.2 board schematic, explain every pinout, highlight common failure points, and show you how to use the diagram to install BL-Touch, dual Z-axis, or even klipper firmware. The official diagram shows the 5-pin probe port

Creality introduced the V2.2 board to reduce stepper motor noise, improve print quality, and support SD card and USB printing with a 32‑bit processor. Unlike its predecessor (V1.1.x with A4988 drivers), the V2.2 board integrates four HR4988‑compatible or TMC22xx drivers in legacy mode, meaning UART/SPI control is not wired by default. If you own a Creality Ender 3 V2,

The V2.2 has only one Z driver output, but two Z motor sockets are wired in parallel. Do not exceed 1.2A total.
