When using the LaTeX package url (\usepackage{url} somewhere in the preamble) which tends to give much more nicely formatted web addresses, the following may be preferred:

 @misc{ wiki:xxx,
   author = "Fixme.ch",
   title = "GPIO relay board --- Fixme.ch{,} ",
   year = "2011",
   url = "\url{http://fixme.ch/w/index.php?title=GPIO_relay_board&oldid=1300}",
   note = "[Online; accessed 18-March-2026]"
