Over time, Creality has released several generations of boards (V2.X, V4.2.2, V4.2.7). While each has its own quirks, the "V2.2" moniker is often used interchangeably with these models. This guide focuses on the , which share similar pinouts and are commonly found in printers like the Ender 5 Plus .

For custom firmware builds (e.g., Marlin), make sure to correctly define the thermistors as 1 (EPCOS 100K B57560G104F). Using the wrong sensor type can create serious risks, including thermal runaway. Creality V2 2 Board Diagram

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.
Unlike newer 32-bit ARM-based architectures (such as the V4.2.2 or V4.2.7), the V2.2 platform utilizes a robust, classic architecture. Over time, Creality has released several generations of
The V2.2.1 has specific IO pins available for modifications, such as LED strip control.
With the community pinout, you can:
If you own a Creality V2.2 board, do not rely on Creality’s official diagram alone . Instead, print a community-corrected pinout and tape it inside your printer’s electronics case. The board itself is decent for silent printing, but its documentation is a weak link—saved only by passionate open-source contributors. What are you installing or troubleshooting this board on
