Günstiges Einsteigermodul, arbeitet bei mir in Kombination mit einer DCF77 Uhr. Angenehm, daß auch der Status ausgegeben/geprüft werden kann (Modul vorhanden bzw. Uhr nicht gesetzt). Einzig das Setzen der Uhrzeit hat etwas gedauert, in meiner Ungeduld die Unterlagen vielleicht nicht genau gelesen. Aber so gehts:

time_t t = now();
if (t != 0) {
RTC.set(t);
