Hello. I am using this motor driver(https://www.robotshop.com/en/cytron-10a-5-30v-dual-channel-dc-motor-driver.html) for a school project. The board tends to heat up and start smelling(burning smell) after prolonged use on the side closer to the input pins. I am currently running it with one Lynxmotion Gearmotor(https://www.robotshop.com/en/cytron-10a-5-30v-dual-channel-dc-motor-driver.html) and was just testing it through the entire speed range and both directions. I am using it with a 12V 8A DC power supply and am connecting everything with 20 gauge Arduino wire(that is what is immediately available to me). Please let me know if there are any immediate issues with this setup, I can provide more information if necessary. Thank you!
