Ich muss hier Mal die Lanze brechen. Wer keine Ahnung von einer Matrix hat und die Art von Carbon Pad das hier genutzt wird, sollte nicht zugreifen und dann schlechte Bewertungen abgeben. Das Teil funktioniert einwandfrei. Man darf nur nicht auf Durchgang messen und hoffen, dass es piept. Mit einer einfachen Suche findet man auch das korrekte Pinout.
