Maximum(Peak) Current: 300mA
Case Material: Polycarbonat(PC)
Case Color: Semitransparent White
Cable Length: 150mm
PCB & Soldering: RoHS, Lead Free (Pb Free)
Wiring: (BLTouch can be operated in the following condition.)
One I/O for control (Orange wire : PWM or Software PWM)
One I/O for Zmin(White wire : endstop / Z-probe)
GND and +5V power
Most Board provides its own servo pin, so BLTouch can be used connected to one of those servo pins. As each servo pin has its own number, BLTouch will be controled with the servo pin number as following.
(Soldering and firmware update might be needed in rare case)
M280 P0 S90 ← SERVO0_PIN
M280 P1 S90 ← SERVO1_PIN
M280 P2 S90 ← SERVO2_PIN
e.g. RAMPS1.4 Wiring
Servo signal(orange wire) : D11 (SERVO0), Zmin (white wire) : D18 (Zmin endstop)
