Rover 5 Motor Driver Board 4WD DC Motor Controlller Board for arduino
(Tow Color random, does not support color options )
Designed originally for theRover 5chassis this driver PCB is ideal for any small robot using either Omni or Mecanum wheels. Current sensing for each motor allows the processor to determine if a motor has stalled or is under excessive load.
Rover 5 controller Features include:
- 4x low resistance FET “H” bridges.
- Each channel rated for 4A stall current.
- Easy to use control logic.
- Current monitoring for each channel.
- Quadrature encoder mixing circuitry.
4 DC Motor Controller Unit Power connectors:
The PCB has two power connectors.One is +5V for logic (Vcc) and one for the motor power supply.The motor power supply should not be connected without first connecting the +5V for logic.This device is rated for a maximum motor supply voltage of 12V. Exceeding this voltage may permanently damage the device.
4 DC Motor Control Unit The encoder mixing circuit:
Unlike most motor controllers this PCB includes 4 mixing circuits for use with up to 4 quadrature encoders. The mixing circuit takes the 2 inputs from a quadrature encoder and mixes them into a single output. Note that the interrupt output changes state when either input changes.
This allows a single interrupt pin to monitor both inputs of a quadrature encoder.Because the interrupt output is twice the frequency of either input it also allows speed and distance to be measured with twice the resolution.
Rover 5 Motor Driver Board Current output:
Each channel has a current sensing circuit. The output of this circuit is approximately 1V for each amp the motor draws (5V maximum). This output can be connected directly to the analog input of any 5V micro controller.
Rover 5 Motor Driver Board logic:
The built in control logic allows each motor to be controlled by 2 pins. Driving the directionpin high or low will cause the motor to run forward or reverse. The PWM pin is used to control the motor speed. When this pin is low, the motor is off. When this pin is high the motor is at full power. To vary the speed of the motor this pin must be PulseWidth Modulated.
Rover 5 Controller Motor output:
Each channel has a motor output socket. Connect any 4.5V –12V DC motor with a stall current of less than 4.5A to these pins. Exceeding 4.5A on these pins may permanently damage this device.
