RedHill Dual Motor Driver Board 12V-50V x 185A
RedHill Dual Motor Driver Board 12V-50V x 185A.
RedHill Dual Motor Driver Designed by Our Team For High Power Brushed DC Motor with current capacity up to 185A peak and 90A continuously Specialized For Mega Sumo Robot.
There are 2 H-bridge motor driver integrated on the board. With this circuit, you can easily use motors with high voltage and current.
In your robotics projects (sumo robot, terrain robot, mars reconnaissance robot, etc.), you can use the circuit that you can use in your R & D works with microcontroller, arduino and all development cards.
Caution ! : No Reverse polarity protection on power source Please ! Check your connection double times.
