A dedicated 5-pin port is often present or can be wired via the breakout board for auto-leveling. Wiring Layout CR-10S Pro V2 specifically, the V2.2 board often connects to a breakout board
| Pin | Signal | MCU Pin | Function | |-----|--------|---------|----------| | 1 | GND | - | Ground | | 2 | 5V | 5V rail | Power | | 3 | Servo (PWM) | PB5 | TIM3_CH2 | | 4 | Probe (Z‑min override) | PC14 | Same as Z‑endstop (must share) | | 5 | GND | - | Ground |
These two-pin white JST-XH connectors read temperatures using 100k NTC thermistors. Measures heated bed temperature. T-E0: Measures primary hotend temperature. T-E1: Measures secondary hotend temperature. 4. Endstops and Sensors
Governed by the firmware to cool the printed plastic layers. This turns on automatically based on your slicer settings.
Screw terminals for the primary and secondary hotend cartridge heaters. 2. Stepper Motor and Driver Layout Creality V2 2 Board Diagram

As Alex's imagination ran wild, they began to envision the board as a thriving metropolis. The GPIO pins were like highways, connecting the board to external devices and expansion packs. The SD card slot was like a bustling port, handling the import and export of files and data. The display interface was like a town square, where the printer's status and settings were displayed for all to see.

The V2.2 board often has two Z-axis connectors, wired in parallel. Ensure both motors are plugged in securely. A dedicated 5-pin port is often present or
Orient the board with the and USB port facing you :
Crucial: The BLTouch probe pin is to the Z‑endstop pin on the PCB. Do not use both physical Z endstop and BLTouch simultaneously without a jumper mod.
The (also known as the Creality 2.2.1 or Atmega 2560 board) is a robust 8-bit control board famously used in larger-format printers like the CR-10S , Ender 5 Plus , and CR-20 Pro . Unlike the 32-bit V4 series found in the Ender 3 V2, this board is built on the Atmel AVR Atmega 2560 architecture, offering more I/O pins for dual extrusion and accessory support. Key Technical Specifications
You are not alone. The community has consistently noted the lack of official documentation for the Creality V2.2 (and V2.1) boards. Datasheets containing max voltages, current limits, and comprehensive pinouts have never been publicly released by Creality. The primary source of truth remains the Marlin and Klipper configuration files. T-E0: Measures primary hotend temperature
Upgrading the Creality V2.2 board with a BLTouch auto-bed leveling sensor requires specific attention to the pins, as the board does not feature a dedicated, unified five-pin BLTouch port like newer 32-bit boards.
to automatically stop heating if temperatures become unregulated. Wiring and Pinout Configuration
When looking at the Creality V2.2 board diagram, you'll notice several key areas:
It's a common question: should you "upgrade" from a V4.2.2 to a V4.2.7?
