Hall Effect Sensor Module KY-003 with SH3144E TO-92

This module adapted for the arduino is a unipolar Ic Hall effect magnetic sensor. The Hall effect is when a current passes through a bar of semiconductor (or conductive) material, and if an induction magnetic field B is applied perpendicular to the direction of current flow, a voltage, called Hall voltage, proportional to the magnetic field, and the current appears on the faces sides of the bar. This tension is proportional to the displacement speed of the charge carriers, which is considerably higher in semiconductor materials than in metal conductors. Hall Effect Sensor Module KY-003 with SH3144E TO-92 features:
- 3-pin connector: 1- GND
2- VCC
3- Voltage is recovered depending on the magnetic effect
- Supply voltage: 5VDC
- Output current: 40mA

DRV8833 Controller DC Motor PAP

Driver DRV8833 can control up to two DC motors or one stepper motor with a constant current of 1.5 A (peak 4A ). The motors are controlled, independently by means of PWM signals the direction of rotation of the motors can be controlled, neutral or stop with a frequency of up to 100 kHz. Two input signals (IN1 and IN2) can be used to control one motor (connected to OUT1 and OUT2) and the other two input signals (IN3 and IN4) to control the second motor (connected to OUT3 and OUT4). NOTE: This DRV8833 dual-bridge motor controller is the replacement for the TB6612FNG dual-channel motor controller. The pins come unsoldered. If the motor draws currents above 0.6A, the use of a heat sink may be required. DRV8833 Controller DC Motor PAP features:
