Wiring:

The BLTouch can operate under the following conditions: One control I/O (Orange wire for PWM or Software PWM), one I/O for Zmin (White wire for endstop / Z-probe) and GND and +5V power. Most boards have their own servo pins, simply connect the BLTouch to one of those. The servo pin number is used to control the BLTouch as follows:

M280 P0 S90 SERVO0_PIN
M280 P1 S90 SERVO1_PIN
M280 P2 S90 SERVO2_PIN

For example, a RAMPS1.4 Wiring configuration would look like this:

Servo signal (orange wire) D11 (SERVO0),
Zmin (white wire) D18 (Zmin endstop)

The package includes the following items:

1. BLTouch Auto Bed Leveling Sensor
2. Two 3pin Dupont Housing Shells
3. Two 2pin Dupont Housing Shells
4. Two 1pin Dupont Housing Shells
5. Ten Dupont Terminals
