Jeremie could you tell me what the component was directly under the yellow poly fuse?
For some reason can't post a pic?

great to hear your very handy.
the yellow part is the diode?
That said, you want to also find out why the component went otherwise it'll just go again.
The component that was damaged, and provided that nice black mark on the polyfuse, was the reverse polarity protection diode. @kamaroman68 it looks like you were operating outside our specifications for maximum continuous current through the ez-bv4.
While I unfortunately can't recommend anything specifically for you, what I can suggest is that you replace the diode with one that meets your specific requirements (keeping in mind that you could face other physical current constraints afterward) or what might be a better idea, you could run power to your high current peripherals (motors, solenoids, etc) external to the ez-bv4.
We can sell the main board itself under special circumstances, though you would have to Contact Us directly. That being said, I feel that you should be able to repair your current main board as a diode failure shouldn't have had any cascading effects. If you'd like to replace the diode with another, please find one that is rated higher than the 6A you need.
