I’m new to this kind of electronics and wanted to test a few things. So I have for interest a battery connected to the Cam M7. There was still a SD card in it and when I connected battery came smoke. So I turned it off. Now nothing seems to work. I have normally connected the cam to the computer but this is no longer recognized. Not from the computer and not from the IDE either. LEDs do not light up when connecting. If I the SD card reinstecke comes again smoke. If I connect the SD card the other way is not a smoke. The SD card no longer works on the computer. Is there still hope?
