When looking at the Creality V2.2 board diagram, you'll notice several key areas:

| Pin | Signal | MCU Pin | Function | |-----|--------|---------|----------| | 1 | GND | - | Ground | | 2 | 5V | 5V rail | Power | | 3 | Servo (PWM) | PB5 | TIM3_CH2 | | 4 | Probe (Z‑min override) | PC14 | Same as Z‑endstop (must share) | | 5 | GND | - | Ground |

Crucial: The BLTouch probe pin is electrically shorted to the Z‑endstop pin on the PCB. Do not use both physical Z endstop and BLTouch simultaneously without a jumper mod.

#define TEMP_SENSOR_0      1    // NTC 100k beta 3950 (hotend)
#define TEMP_SENSOR_BED    1    // same for bed

Bottom line:
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.

Recommendation: Before any wiring mod, verify your board revision and cross-reference at least two community diagrams from GitHub or r/ender3.
