I have my mega 2560 with the shield ramps 1.4 at the same time with usb and power supply connected. Suddenly rises smoke and my mega 2560 broke. I thought I could use it at the same time, because for usb I connect with the computer and with the power supply I drive the engines and the heating bed. , Then I ordered a new one, because I thought that the mega 2560 might not have worked properly before, but it went back into smoke. I have already looked in many forums and have read that you can connect it at the same time. Can someone tell me what I do should now?
What part did the smoke come out of?
Unfortunately I do not know where the smoke is coming from because my board ramps 1.4 was above. But the chip atmel at mea 2560 16au 1642 becomes after some time very hot, when it connect with the computer.
I'm sorry I do not know how to insert a picture forums else I would have sent a photo from my board.
Hello,
the second board was broken, too.
Now it goes.
