Schrittmotor: bipolar, 200 Schritte/Umdrehung, 57 x 56 mm, 2,5 V, 2,8 A/Phase hub-sensoren s output pulse width resolution

s output pulse width resolution (corresponds to approximately 0

Each phototransistor is connected to a pull-up resistor to form a voltage divider that produces an analog voltage output between 0 V and VIN (which is typically 5 V) as a function of the reflected IR

Small and lightweight module

s A4990 is a dual H-bridge motor driver IC that can be used for bidirectional control of two brushed DC motors at 6 to 32 V

Schrittmotor: bipolar, 200 Schritte/Umdrehung, 57 x 56 mm, 2,5 V, 2,8 A/Phase hub-sensoren s output pulse width resolutionThis high torque hybrid bipolar stepper motor has a step angle of 1. 8 (200 steps revolution). Each phase draws 2. 8 A at 2. 5 V, providing a holding torque of 13 kg cm (180 oz in). The motor has four color coded wires with bare leads: black and green connect to one coil, and red and blue to the other. It can be controlled via a pair of suitable H bridges (one for each coil), but we recommend using a bipolar stepper motor driver. Our 6. 35 mm
