Generell ein schönes Set, leider fehlte bei uns ein Kondensator den wir zum Glück noch Zuhause hatten, für andere wäre es aber wohl an der Stelle vorbei gewesen. Es gibt keine beiliegende Anleitung, nur ein Bild in der Produktbeschreibung in schlechter Qualität, man findet aber im Netz einige PDFs dazu.

The component density is quite high and suggests that considerable time was invested in the layout design of the PCB. The circuit design, which is published, is clever to the point of being elegant. Quality of PCB and components very good.
