Need to see if there is a chart showing what power levels I should see at the various pins and components on the U3S.  Just built another and have the dreaded one line of blocks show up.  Already checked the usual suspects - power, crystal, soldering (visually checked so far)...Would like to troubleshoot further.  thanks - Jeff, AC7IJ
