Creality V2 2 Board Diagram Fixed Jun 2026

| Issue | Possible Cause | Solution | | :--- | :--- | :--- | | | Corrupted firmware or improper bootloader | Re-flash firmware using ISP programmer or USB | | Extruder Motor Won't Move | Burnt inductor (L3) or bad stepper driver | Replace inductor or stepper driver | | Hotend Won't Heat (or Stays On) | Failed MOSFET (Q1) | Replace MOSFET or use spare heater port (HEATER1) | | BLTouch Not Deploying | Wiring mismatch or incorrect pin mapping | Double-check wiring and firmware pin assignments (Control: PB5, Sensor: PD3) | | LCD Shows Garbled Text or "No Printer Attached" | Wrong firmware version or damaged LCD cable | Re-flash correct firmware; replace LCD cable |

The layout of the V2.2 board is distinct from the 32-bit V4.2 series. Understanding the primary connections is essential for troubleshooting or upgrades. CR-10S with Mainboard V2.2 BL Touch - Thingiverse

// Endstops #define X_STOP_PIN PA4 #define Y_STOP_PIN PA5 #define Z_STOP_PIN PA6 // Unused if BL-Touch enabled Creality V2 2 Board Diagram

The diagram shows a 0-ohm resistor (R100) near the driver that bridges the UART pin. If R100 is populated, you can enable #define TMC_DEBUG in Marlin.

Unlike the Ender 3 which uses a single ribbon cable, the classic CR-10S layout on the V2.2 board requires two ribbon cables ( and EXP2 ) running to the LCD screen screen. Ensure they are not swapped, or the screen will chirp and remain blank. Upgrading the Creality V2.2 Board | Issue | Possible Cause | Solution |

Below is the standard pinout diagram. You can right-click and save this image to print it out on paper.

Best find: The "V2.2 Board Pinout Guide" by user dmbutyugin – includes exact GPIO numbers for custom firmware builds. If R100 is populated, you can enable #define

Mastering the transforms you from a casual printer user into a hardware hacker. You learn to read silkscreen labels, trace MOSFET gates, identify shared pins, and safely override firmware limitations.

For Klipper users, here is the necessary printer.cfg configuration for the Creality V2.2 board. These pin numbers are taken from the official Klipper example configuration:
