The Vyper 120A DC Motor Controller is a flexible high-performance single channel motor controller for medium to large mobile robots such as firefighting robots, sumo, robotic combat, theater props, inspection, EOD and other applications. It may be used on robots up to as much as 500 pounds or more as long as the motor current limits are respected. Also, the Vyper supports manually controlled ''throttle'' applications such as scooters, boats, winches and others using a potentiometer or other analog voltage control. Similarly the Vyper is suitable for applications including lights, hydraulic valves, pumps and other non-robot uses.

Very reliable and easy to program

It is easy to control and program. I use it on a truck carrying heavy equipment with a potentiometer 0-5K (electric bike). The configuration and schematic instructions provided are clear.

Vyper 120A

I am using this motor controller with a 24V geared motor to drive the feed and carriage return on a homebuilt band sawmill. Initial hookup and programing was interesting to say the least as we are using a potentiometer to control forward and reverse speed. The instructions for setting up the programing using the DIP switch were somewhat confusing for this manual control approach and it took quite awhile of trial & error to get the switched in a configuration that worked. Once configured the unit works great but instruction sheet could be greatly improved.

Vyper 120

Use this module on a sawmill feed carriage, works real good !! I had originally chosen an other type with more features and cheaper but was not available so I went with the Vyper 120. Instructions sheet could have more details but RobotPower answered all my questions same day.
