I think, there is still no easy way to describe your littleBit designs. One issue is the availability of the different modules as symbols or picture files to put them together in a power point, word or other drawing program.
Not the easiest way, but with reasonable effort, is to use a program like inkscape to export image files or even vector graphics ( svg ).
As an example I have attached the extraction of the remote trigger bit. I could not use the svg file in my favorite drawing program, visio under windows, but I could still use the extracted .png file.
Is this approach reasonable ?
And, is this legal ?
