Creality V2 2 Board Diagram Fix

Dedicated Pulse-Width Modulation (PWM) terminal used exclusively for the layer part-cooling fan. 2. Stepper Motor Ports (Top Edge)

JST connector (usually wired to be always on).

Carefully touch the positive (red) probe to the small metal potentiometer screw on the driver you want to adjust. X / Y Axes: ~0.9V to 1.0V Z Axis (Driving dual motors): ~1.1V to 1.2V Creality V2 2 Board Diagram

Main 24V DC power input from the power supply unit (PSU).

There is no official "Creality V2.2 diagram" from the manufacturer, but the community has produced one through meticulous effort. The following list represents the pin mappings used by Marlin and Klipper. Carefully touch the positive (red) probe to the

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.

Ensure your power supply is completely unplugged from the wall. Connect the thick red (+) and black (-) wires from your 24V PSU to the main power terminal blocks. Double-check polarity; reversing these will permanently damage the board. Step 2: Heating Elements The following list represents the pin mappings used

The (and associated V2.x variants) motherboard is a crucial component found in many popular Creality 3D printers, including the CR-10S , CR-20 , Ender 5 Plus , and Sovol SV01/SV02/SV03 . While newer 32-bit boards (like the V4.2.2 or 4.2.7) are now standard on new Ender 3 models, the V2.2 board remains a workhorse for robust, dual-Z-axis machines.

3-pin port to detect when the printer runs out of filament. 4. Thermistors (Left Center) T_BED: 2-pin port for the 100k NTC bed thermistor. T_EXT: 2-pin port for the 100k NTC hotend thermistor. 5. Fans and Displays (Top Edge & Center)
