  • Have you tried running it on 5v? There is an on-board regulator, and the core is a 3v3 chip(I think), so 3v3 into the regulator, and asking for 3v3 out of the regulator might be causing problems. I am borrowing from old linear regulators - the input voltage must be greater then the wanted output voltage. If the core is running at 3v3, you have to feed it more then that as a power source, UNLESS you bypass the regulator…

  • Specs say you can use 16 character filenames such as 123 ABCDEFGH.TXT, which is just fine, but Datasheet pages say you can only use 8-dot-3 names. Can someone clarify? Thanks. :)

No public wish lists :(
