For a sampleslicer DIY kit go to the presale on my website.
This kit is easy to build, but is not suitable as first soldering project. Some parts don’t have much space to for clumsy soldering. You need a soldering iron with a small pencil point and a good cutter. But don’t let this scare you off as all SMD parts are already in its place and you don’t have to do any programming.
For information about the module see Sampleslicer.
