RTC-Modul DS3231

Alles so wie es sein soll.

By: Am: 13 May 2022

Gutes Modul mit kleinen Abstrichen

Zunächst einmal ist das Modul eine Quelle um günstig an einen DS3231 heranzukommen. Bei den üblichen Distributoren wird meist das doppelte alleine für den nackten DS3231 aufgerufen.
Für Low Power Anwendungen muss das Board allerdings modifiziert werden.
Die LED ist meiner Meinung total sinnlos und ein EEPROM hat heute jeder Mikrocontroller integriert. Aber es ist halt gratis dabei und wer es nicht braucht, kann es von der Platine löten.
Ob der ausgesprochen preiswerte DS3231 die gleiche Genauigkeit liefert wie die teuren von einem namenhaften Distributer muss er erst beweisen.
+-2ppm sind eine echte Ansage. Mal sehen, wie die Abweichung nach einigen Monaten aussieht!

By: Am: 2 May 2022

Alles bestens!

Schnelle Lieferung, beide Module habe funktioniert, besser geht es nicht!
Ein Li-Akku muss separat bestellt werden.

By: Am: 1 May 2022

Qualität ist gut, es muß aber ein Akku verwendet werden oder man muß die Diode entfernen.

Ein Hinweis das ein Akku verwendet werden muß und keine Batterie

By: Am: 31 Mar 2022

Zur Stromversorgung kann ein Akku verwendet werden.
