PN00218-CYT9 Cytron Dual-Channel 10A Motor Driver + Arduino IDE Compatible ATmega328 Microcontroller + Sensor Interfaces All-in-one Sumo Robot Board URC10

Extremely upset with this board. I purchased it to build a sumobot for my final project in my Amps II class in college. Had issues with the left wheels not working all the time and thought it was my coding at first. Had my professor check my coding and it was good. No issues. The night before my final is due, I power up my sumobot just to make sure the sensor ranges are set where I want them and the left wheels would not work. M2A and M2B connections were getting power, just not making it to my wheel. I dont know if there is a short, or a chip is fried, but I'm three hours away from turning in my final and it doesnt work.tried to order another just to turn my project in late and a new one will not arrive until next week. My project grade just went from an A to an F because of this defective product. I will never order from this company again.

I have been using this board for the past year in several high school robotics classes. 16 boards used daily, two 12V motors attached, multiple sensors and lights...under trying conditions with students. So far, only two boards have failed. One smoked from what appeared to be a bad Mosfet and the other had its USB connection fail. Other than that, solid board for the money and the only good option that I found allowing 12V motors. If you are worried about failure, a few dollars can get you a spare.
