Many of our products is designed to be mounted on a DIN rail or at least they have an option to be mounted in this convenient way. There are a number of advantages with the DIN rail as mounting tool. The most important is the vast choice one get if one want to mount equipment in boxes of various sizes and IP classes. You can mount things outside in harsh environments or on a more dry and forgiving office wall just as easy.
The Raspberry Pi DIN rail mount kit, which now is available in the frogshop, makes it very easy to mount a Raspberry Pi card either horizontally or vertically on a DIN rail. The kit contains everything you need to get the job done. There is a possibility to mount a DC-DC module (like this one) under the Raspberry Pi card to power the Pi.
