HiLetgo 4pcs L298N Motor Driver Controller Board Module Stepper Motor DC Dual H-Bridge for Arduino Smart Car Power UNO MEGA R3 Mega2560

Used the L298N to test a stepper for a CNC machine. Worked perfectly. I did need to research the pin out which waa well documented on the internet.

They arrived and what I had ordered

So far I'm only using this to drive a small linear actuator with an Arduino and it does the job well. All of the heatsinks on my units are fully connected so no obvious issues with quality from my experience. Getting 4 for this price was just a bonus.

Arrived as described, fast delivery, quality component. Used to control motors on a hobby model car. Satisfied with performance. Would buy again.

These are great little modules for the price. Easily control speed and direction of two DC motors or parallel the outputs for more current. The only problem I had was with the poor quality control of the heatsink attach. There was a significant gap between the heatsink and the thermal tab. There is also no thermal grease or thermal pad between the heatsink and the tab. This caused the part to overheat with just 30% of specified loading. Fortunately, the solution was simply to torque down the screw until the tab was pulled tight against the heat sink. There was a smaller gap on all the modules I purchased, each slightly different which indicates poor process control. Also, I recommend injecting a small amount of thermal paste in the gap prior to tightening the screw. This will significantly improve thermal conductivity to the heatsink. If not for these issues I would have rated this a 5 star.
