Enable is active LOW (GND = enabled).
Note: Fan voltages depend on the board revision; early V2.2 boards use 12V fans with a 24V→12V linear regulator; later revisions use 24V fans directly.
Located along the top edge for X, Y, Z (dual ports often available), and Extruder (E) axes. Limit Switches: 3-pin headers for X, Y, and Z endstops. Heating & Power: Power Input: 12V/24V screw terminals. Hotbed: High-power screw terminals. Nozzle Heater: Screw terminals for the heater cartridge.
The V2.2 typically takes 12V or 24V depending on your printer model. Ensure proper polarity (+ and -). Hotend Heater: HEATER0. Heated Bed: BED (10-pin block or thick screw terminals). D. BLTouch / CR Touch Installation

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:
If you are replacing your old board or migrating to a new chassis, follow this order of operations to prevent shorts or damaged components. Step 1: Power Inputs (Safety First)
Often uses A4988 drivers, which are pluggable on some V2.2 versions, or soldered on others. Heaters and Thermistors
