Vintage computers seller, [Pakequis], has designed a universal prototyping board, called ProtoConn, which features every connector they could think of including analogue, serial, USB headers, and many microcontroller board and Arduino shield footprints.
The board is an advanced version of the usual breadboard used for teaching electronics and could provide a useful alternative to multiple commercial circuit boards.
Previous versions of the all-in-one prototyping board have been featured by Hackaday in 2012.
The article’s commentators have pointed out some notable omissions, including a fuel nozzle connector in honor of the xkcd cartoon.
