Hi,
just after assembling I had the following symtom, after a vacation it worked for two days and now I have
the symtom again:

If I use a variable powersource my uBITX v5 (at least the Radiuno) works up to a voltage of 5-6V.
After that the display freezes (Pic1).

If powering on at higher voltages like 13,8V I get the following (Pic2):


Anyone knowing whats going on here?

Thanks in advance!
