L298n dual h bridge motor driver fritzing

One side pin of the potentiometer (either one) to ground the other side pin to +5V Speed and direction controlled by a potentiometer attached to analog input 0. IBT-2 Motor Control Board driven by Arduino. In this post I describe a slightly more complete solution that uses an Arduino controller with connected potentiometer to drive a motor via the IBT-2 module from full reverse speed to full forward speed.įor reference here is the description of the input ports and the two supported usage modes (image taken from one of the ebay postings).

This thread on the Arduino forum was useful but the solution wastes a few pins and does not demonstrate bidirectional motor control. I am not sure whether the heat sink is sufficient for handling 43A but even if one does not drive the unit to its limits the specifications are still impressive given the typical price point of this module (currently between $13 and $17 including free shipping from China). There is relatively little information available about how to hook up the module with an Arduino controller. The link provides more details but here are a few key parameters.

The IBT-2 H-bridge module from wingxin is an inexpensive, high power motor driver based on two BTS7960 chips and is readily available from various ebay vendors see e.g.
