Your cart is empty.4 Channel DC Motor Controller with Encoder Support Each channel is rated for 4A of stall current and each channel has its own current monitoring circuit. Low resistance FET "H" bridges ensure high efficiency and good motor torque. Built in control logic allows each motor to be controlled by 2 pins. One pin for speed and one for direction. As it is specifically designed for the , the PCB includes a quadrature encoder mixing circuit. The mixing circuit takes the 8 inputs of the 4 quadrature encoders and generates 4 outputs. These outputs are suitable for interrupt generation and high resolution speed control. This compact PCB is just 95mm x 70mm (3.75inch x 2.75inch) and is a perfect companion for the Spider robot controller. --Features-- •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.-- •Includes mounting hardware-- --Documents-- • •

This looks like an excellent board with great features BUT THERE SEEMS TO NOT BE ANY DOCUMENTATION available for it. This was used in Dagu's Rover 5 robot platform. Without documentation, this board is USELESS.

The design of this four 12V DC motor controller is very good.It will work with any SBC sending controlling signal and receiving PID feedback from the four motor encoders.Unfortunately, I could not find a tutorial, or a schematic on how to connect and program it other than a very basic two page generic description of all the pins.

This is a great motor driver board for the price. This board can be used with any set of DC motors and you don't need to use the Rover 5. I use it with Pololu gear motors with encoder and it works great. I also use Teensy 3.6 to control it.Here is the mating connector for the motor outputs: VHR-3NDon't forget these too: BVH-21T-P1.1

This controller works with the Rover 5 robot platform both the two motor and 4 motor version. You need this controller for the Rover because I have read the motors have a high current load for turning them on. I suppose there are other work around measures, but I decide to use this one. However, on reading up on it there was an issue where you must turn on the logic power from your micro-controller or Raspberry Pi computer first before the power for the motors. The risk for not doing this is damage to the controller. A switch for the batteries is one measure of protection provided you not forget and turn it on before powering the logic power to the board. Also what happens if the switch accidentally gets turned on? I added another fail-safe with a Radio Shack IRF510 Mosfet Transistor. Placing power from my Arduino UNO to the gate and a 1 meg ohm resistor to ground. The source will go to ground and the wire from the drain will go to the negative (GND) battery port of the controller. The positive lead from the battery to the positive battery port of the controller.
