How to get it
Assembled Boards
Get Gen7 Endstops from [1] in the assembled boards category.
PCBs
Get Gen7 Endstop PCBs from Traumflug.
As Gen7 is designed to be manufactured on a RepRap or by other DIY methods, you can make PCBs yourself, of course.
Yet another way is to purchase from one of the many houses specialized in manufacturing prototype PCBs. Gen7 is single sided, so this won't cost a fortune.
Electronic components
Get Gen7 Endstop Components Kits from Traumflug.
If you want to assemble the collection yourself, see the #Parts List section.

Assembly Instructions
- To find out which components to put where, have the layout on your PC screen available.
- PCBs fabricated with Voronoi paths need more heat, so raise your soldering iron's temperature by about 20 deg Celsius.
- Start with the flattest parts, usually wire bridges or resistors. This way, components won't fall out when you lay the PCB on it's front for soldering. Then continue with parts of raising height, connectors are usually among the last ones.
- To ease soldering jumper headers and similar components, put a small drop of cyanacrylate glue onto the component side before inserting them. As the PCB is single-sided, this won't hurt the solder point.
- Take care to not overheat the photo sensor. Solder one pin on each side then pause for a minute before continuing.
- As LEDs have to be inserted the right way they have legs of different length to indicate polarity. The longer leg (+) goes into the hole closer to the photo sensor and the shorter one (-) into the hole closer to the border.
