Below you will find stuff from raw PCB's (Printed Circuit Board) to half-finished BI8 boards and LP11 buttons. Only buy the stuff if you know you need it after having been around my development wiki where I keep information for "makers" up-to-date.
Wonder if you can take on the job of creating a "BI8" board yourself? Well, watch this video and you will get a good idea about how complex or not it will appear to you. Basic skills will include soldering and in this case soldering really tiny components. However, with a good soldering iron, a steady hand and some additional tools and tricks its absolutely possible. Generally you can find information about the products and how to create them on the wiki pages. [Video coming up soon!]
