Grija

Un datasheet : https://www.e-gizmo.net/oc/kits%20documents/TinyRTC%20I2C%20module/TinyRTC%20i2c%20module%20%20Techincal%20Manual%20rev1.pdf
Pentru a functiona corect modulul are nevoie de un acumulator Li-ion 3V 2032. Si pot si eu sa confirm ca trebuie schimbat cuartul de pe placa. la 9 ore am deja 1 minut in plus ceea ce e foarte mult. O sa incerc sa schimb cuartul actual cu 32.768khz.. Pentru cei ce nu gasesc acumulator exista tutoriale cum sa modifici placa pentru a functiona cu baterii de 3v https://www.dipmicro.com/store/DS1307BAT-MOD

Necesita modificari hardware

Cumparati cristal de 32.768kHz de pe site si inlocuiti-l pe cel de 30kHz de pe placa altfel va alegeti cu secunde delay la fiecare minut. Necesita acumulator LIR2032 de 3.6V pentru ca are circuit de incarcare, daca lasati bateria CR2032 de 3V, in timp va crapa.

Bun, dar cu acumulator nu cu baterie!

Este un modul ieftin dar care-si face treaba bine. Mare atentie insa ca modulul este facut sa functioneze cu acumulator LIR2032 de 3.6V sau ML/VL2032 de 3V nicidecum cu baterie CR 2032. Bateria va crapa in timp din cauza ciclurilor de incarcare ale modulului. Versiunile mai noi au acum acumulator inclus.
