Creality V2 2 Board Diagram Direct
This is a detailed technical paper on the Creality V2.2 Silent Motherboard (often referred to as the 4.2.2 or V2.2 board), focusing on its schematic layout, component identification, and functional block analysis. This document is intended for educational purposes, firmware development, and hardware troubleshooting.
10. Conclusion
The Creality V2.2 board is a capable 32‑bit silent controller for Ender‑series printers. Its design is simple, well‑documented by the community, and highly repairable. However, firmware developers and advanced users must be aware of:
- The shared Z‑endstop / BLTouch probe pin.
- The SD card CS conflict with X_DIR.
- Standalone stepper drivers (no current adjustment via software).
- 12V vs 24V fan compatibility between revisions.
With the provided pin mappings and power schematic, anyone can repair, upgrade, or port custom firmware to this board. Future revisions (V4.2.7) address most of these hardware quirks, yet the V2.2 remains a reliable workhorse for thousands of printers worldwide.
✅ Pro tip
Always keep a copy of your original firmware and a reference photo of your board’s wiring – especially before unplugging anything.
Creality V4.2.2 32-bit mainboard is the standard factory board for the Ender 3 V2 and Ender 3 Pro. While versions may vary between "silent" (TMC drivers) and "non-silent" (A4988 drivers), the physical layout and pinout for connections remain nearly identical. Core Specifications : 32-bit ARM Cortex-M3 (STM32F103) running at 72MHz. : Supports 24V power input.
: Varies by batch; look for a letter on the SD card slot to identify: : HR4988 (Non-silent). : A4988 (Non-silent). : TMC2208 (Silent). : TMC2209 (Silent). Port Layout & Connection Guide

(often designated as version 2.2.x) is an 8-bit mainboard powered by the ATmega2560 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.
Unlike standard Ender 3 boards, the V2.2 series was designed to handle more complex printer configurations, including dual Z-axis motors, filament runout sensors, and auto-leveling probes. Key Features of the Creality V2.2 Board Processor: 8-bit ATmega2560.
Stepper Drivers: Often equipped with TMC2208 "silent" drivers in its V2.2.1 iteration, though some variants used standard A4988 drivers.
Voltage Support: Typically operates on a 24V system, which provides more power to the heated bed compared to older 12V boards.
Expansion: Includes a dedicated 30-pin daughterboard connector for the CR-10S Pro series and D11 pins for BLTouch integration. Creality V2.2 Board Pinout & Diagram Overview

Abstract
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.
5.2 Critical Components on Power Path
| Component | Function | Failure symptom |
|-----------|----------|----------------|
| F1 (PTC) | 24V input fuse (resettable ~6A) | No power at all |
| MP1584 | 5V buck converter | No 5V -> blank LCD, no USB |
| AMS1117‑3.3| 5V→3.3V LDO | No 3.3V -> MCU dead, boot fail |
| D1 (diode) | Reverse polarity protection on 24V | PSU polarity protection |
Always verify 24V input polarity – red to VIN, black to GND. Reversing will blow D1.

1. BLTouch / Probe Port (J-Tag)
If you are installing a BLTouch on the dedicated 5-pin port:
- Pin 1 (Closest to edge): GND (Ground) - White/Brown wire usually
- Pin 2: GND (Ground)
- Pin 3: PC14 (Signal) - Orange wire usually
- Pin 4: PA1 (Probe/Z-Min) - Yellow wire usually
- Pin 5 (Closest to CPU): +5V (Red wire usually)
