The board has specific connectors for hotend and bed heaters, as well as for thermistors to monitor temperature. Correctly connecting these is crucial for temperature control.
Supports either 12V or 24V DC (determined by your machine's power supply units).
Features thermal runaway protection enabled by default. Mainboard Diagram & Wiring Layout
: Compatible with both 12V and 24V power inputs, making it versatile for different Creality power supplies. Creality V2 2 Board Diagram
(V422 refers to V4.2.2 board)
This is where you connect your 3D printer's power supply. Make sure it's compatible with the board's voltage requirements.
Controls the primary axes. The V2.2 board features dual Z-motor ports wired in parallel, ideal for keeping wide gantries level. The board has specific connectors for hotend and
Fans are generally split into "always-on" (hotend) and "controlled" (part cooling).

High-Power Terminal Block (Bottom Row) Features thermal runaway protection enabled by default
The official name is printed on the bottom side. The top side shows a large “CR-FDM-v4.2.2” silkscreen. Do not confuse with V4.2.3 (different MCU pinout).
Navigating the dense thicket of wires inside your control box requires a precise understanding of the physical board layout. The terminal blocks and ports are structured across specific zones:
Are you planning to install this board as a for an existing one, or are you upgrading a printer to silent drivers for the first time?
