DGU 4CH 4,5A MOTOR CONTROL BOARD

SKU: DGU 4CH 4,5A MOTOR CONTROL BOARD

BRAND: Dagu


RS011MC Rover 5 Chassis DC Motor Controller Board 4 Channel @ 4.5A each with Encoder Support

Overview

  • This motor driver board, originally designed by Dagu for their Rover 5 platform, is ideal for any small 4-wheel drive robotic vehicle
  • With four motor outputs, four encoder inputs and current sensing for each motor, it's a must-have when implementing omni or mechanum wheels
  • The motor drivers can be controlled by simply applying a logic 0 or 1 to the direction pin for that motor and a PWM signal to the speed pin
  • In this way, the speed and direction of four separate motors can be controlled independently from only 8 GPIO pins
  • The encoder inputs on the driver board mix each pair of encoder inputs using an XOR gate making it possible to read both inputs from a quadrature encoder using only one interrupt pin
  • Reading the current sensor output is easy, each current sensor pin will output about 1V for each Amp of current drawn by the associated motor up to 5V
  • Connect the current sensor pin to the analog input of your controller and you'll be able to detect stalls and other motor problems
  • There are two power connectors on board : One is for 5V logic and the other is the Motor Supply
  • Be sure to turn on your logic supply before applying the power source for your motors
  • The board is rated for a maximum motor supply voltage of 12V
