above exactly 1.0A @ 5.0v, housings are ***REQUIRED*** to cut power without warning.
This seems like a broken spec to me. Nothing in electronics is exact, so a sane spec should have a reasonable margin between the maximum current a card is allowed to draw and the point at which overcurrent protection is required to kick in.
appreciated - very good point this is the first time it's really been discussed. i'm already uncomfortable with the idea of having 5.0 watts in an enclosed space. 3.5 is okay. i _was_ thinking of raising the Housing limit to 5.5 watts, but was slightly concerned that people would abuse the extra headroom.
suggestions appreciated.... hmm... let me just add a section on the specification / discussion on the elinux.org talk page to reference this discussion...
