Creality V2 2 Board Diagram Now

Marlin 1.1.x / Marlin 2.0.x (8-bit environment)

If your motors are moving in the wrong direction, you can flip the connector 180 degrees on the board.

| Symptom | Likely cause | Test point / fix | |---------|--------------|------------------| | No power, no LED | Blown PTC fuse (F1) or reverse polarity diode D1 | Measure 24V at J1; check continuity across F1 | | LCD backlight on but blank | 5V missing or LCD ribbon loose | Measure 5V on EXP1 pin 1; re‑seat cable | | Steppers not moving | Enable pins low? Check 24V to drivers | Measure 24V on CN14‑CN17 pin 1; check EN pins (should be ~0V) | | Hotend won’t heat | Dead MOSFET (Q2) or no 24V | Measure voltage at CN8 while M104 S200; if 0V, replace MOSFET | | Bed won’t heat | Dead MOSFET (Q1) or thermistor short | Measure resistance across bed (≈3Ω for 24V); check MOSFET gate from MCU | | BLTouch fails to deploy | No 5V or PWM pin | Measure 5V between CN18‑2 and GND; PB5 should toggle 50Hz | | Random resets during print | 5V rail droops (buck converter overheating) | Add heatsink to MP1584; limit part fan if sharing 5V | | USB not recognized | Dead CP2102? (no – board uses native USB) | Check if PA11 (USB_DM), PA12 (USB_DP) have correct impedance; reflash bootloader | Creality V2 2 Board Diagram

| Endstop | MCU Pin | Internal Pullup | |---------|---------|----------------| | X‑min | PA1 | Yes (10k) | | Y‑min | PA0 | Yes | | Z‑min | PC14 | Yes |

Are you trying to (like BLTouch) or troubleshoot a specific problem ? Marlin 1

In this deep-dive guide, we will dissect the official Creality V2.2 board schematic, explain every pinout, highlight common failure points, and show you how to use the diagram to install BL-Touch, dual Z-axis, or even klipper firmware.

Use the labeled ports X-MOT , Y-MOT , Z-MOT , E0-MOT . (no – board uses native USB) | Check

~1.1V to 1.3V (depending on if you use a lightweight pancake motor or stock stepper).

depending on your power supply. Ensure polarity (+/-) is correct to avoid frying the MOSFETs. ATMega2560 Chip:
