Beschreibung

L9110S Schrittmotortreiber für z.Bsp. RepRap 3D Drucker (H-Brücke)

Eigenschaften:

  • L9110S
  • Arbeitsspannung: 2.5-12 Volt
  • Die Arbeitsspannung ist gleichzeitig die Arbeitsspannung für den Motor
  • Arbeitsstrom: 800mA pro Phase
  • Freilaufdiode integriert
  • Arbeitstemperatur 0-80°C
  • Größe 27x20,5x15mm

Das Modul kann 2 DC Motoren oder ein 4 Kabel Steppermotor betreiben.

Arduino:

 

#define L9110_B_IA 10 // D10 --> Motor B Input A --> MOTOR B +

#define L9110_B_IB 11 // D11 --> Motor B Input B --> MOTOR B -

 

// functional connections

#define MOTOR_B_PWM L9110_B_IA // Motor B PWM Speed

#define MOTOR_B_DIR L9110_B_IB // Motor B Direction

 

// the actual values for "fast" and "slow" depend on the motor

#define PWM_SLOW 50  // arbitrary slow speed PWM duty cycle

#define PWM_FAST 200 // arbitrary fast speed PWM duty cycle

#define DIR_DELAY 1000 // brief delay for abrupt motor changes
