Schöne kleine Module für Spannungswandlung. Die ersten 3 Module hatten bei 5 Volt Einstellung nur 3.8 Volt. Musste die Spannung via Adj Brücke mit Potentiometer einstellen. Die restlichen 7 Module habe ich direkt via Adj. gemacht. Genaue Einstellung ist schwierig wegen Auflösung Potentiometer. Werden kaum warm. En muss auf Eingangsspannung gelegt werden. Lange Transportzeit (mehr als 40 Tage). Sind jetzt im Dauertest. Bin zufrieden.
