    Works good so far

    Works good so far
    Have tested this microcontroller with driving motors and solenoid valves, and it works well with the L293 motor shield (which is why I got it). I think it is fairly priced for the level of quality, it seems quite well made. I just need to figure out how to use it outside of Arduinos IDE and then it will be perfect.4/5 for me.
