Re: QMX rev 2 build dead and does not boot

Also, first check to see if the 12V input to the 3.3V regulator board comes up when QMX is told to turn on.

Frans,? I would begin by looking carefully around IC101, the 78M33 3.3V linear regulator. What voltage do you see at each of its three terminals?
JZ KJ4A?
Hello,
I have build a QMX rev2 but when I connect 12 volt nothing happens no current also not when I press the left rotory
It is completly dead also no usb device is detected at the computer, I see also no voltage at l202 to the micro contraller.
This my ever first kit wiich did not work i have build several such as QDC XCQ en WSPR tx GPs etc
I am a bit lost how to go forward where should I start? At the buck converter i see only 12 volt
Who can help me to get it working, or some testplan to proceed
