In order not to repeat the command analogWrite (), can I put an if statement that updates the pwm provided for reference only when the value changes, right?
Wow, that is a very impressive motor driver for the price, I'll have to think about getting one of those.Lefty

Probably handle 15A nicely though.
It may have a heatsink on the bottom, but the devices are on the top and FR4 PCB material is not a good conductor of heat.I presume there are lots of vias under them but not 30W's worth!If it were an aluminium PCB that might be difference, but its clearly FR4 from the edge in the photo, and has through-hole components to prove it.
