  • Four jumpers H low resistance based on the FET
  • Current consumption: up to 4 a per channel
  • The simple control interface
  • The voltage measurements for any engine
  • Inputs for sensors kwadraturowych


On the Board there are two power connector:

  • the power logic controller 5 V
  • powered engines 12 Volt

It should be borne in mind to power the logic part of the front of the engine feeds.



  • 4 channel driver of the Rover 5 motors
  • Mechanical items for installation of tiles


A module that allows you to control up to four DC motors. Has inputs for sensors and sensors to the current flowing through each of the supported engines.


Service driver

The management module can be implemented in a simple manner by filing a logic 0 or 1 on the pin that determines the direction of rotation. The rotation speed is set via a PWM signal. In this case, to control the four engines used eight GPIO pins.


The sensor inputs of

Inputs enkoderowe are subjected to the logical operation XOR, which allows us to serve two signals from the sensor kwadraturowego through a single pin interrupts.



The figure shows the principle of operation of the zones of the sensors kwadraturowych.


Measuring amperage

Read the measured current flowing through the motors is implemented by measuring the voltage, where 1 V corresponds to 1 A (5V). The output of the current sensor should be connected to terminals of the Converter an analog-to-digital (analog pins to Arduino). Current measurement allows to detect a lock of the motor shaft or other related problems of the engine.
