Reloj preciso, Batería no sustituible
Es un buen modulo de reloj, y bastante preciso 1-2 segundos mes, el inconveniente esta en la pila, soldada directamente al circuito, debería estar provisto de un zócalo intercambiable, en mi caso al cabo de un año, la batería se agoto

Bad accuracy
Build quality of these RTC modules are OK as well as the battery, but the RTC chips used are scraped units from manufacturer/production. The accuracy (keep time accurate) is realy bad. Clock should be 32768Hz, but are closer to 32622Hz -> some -4000ppm or >300sec per month wrong. Haven't measured all of the 4 modules, but I doubt they are even close in accuracy as good batches from IC manufacturer...

funzionano bene
Clock per Raspberry perettamente funzionante

Works like a charm!
Good communication and professional seller. Really satisfied with the durability and compatibility for the RPI4.To connect this and get it to work with LibreElec on RPI4, just follow these simple step-by-step instructions!1. Unplug your Pi and Install the RTC module onto the GPIO connector pins 1-42. Switch your RPi back on and SSH into itEnable kernel support:3a. Remount LE system partition r/w with this command: "mount -o remount,rw /flash"3b. Edit the config with this command "Nano /flash/config.txt" and add (somewhere near the end): "dtoverlay=i2c-rtc,ds3231"3c. Remount LE system partition r/o with this command: "mount -o remount,ro /flash"3d. Then write the command "Reboot".4. Adjust the RTC's time:4a. Verify local system time with the "date" command. If local time is off, either adjust it manually or connect your Pi to the Internet and wait for it to the the correct time from an NNTP server.4b. Transfer local time to RTC with command: "hwclock -w"4c. Verify RTC time with command: "hwclock -r"That's it. You're done. Your LibreElec RPi will now have the correct time every time it powers up.

Voila comment être a l'heure sur sont Arduino
Bonjour,Horloge pris pour mon arduino. J'avais besoin de cela et ca fonctionne parfaitement. C'est tout petit en plus.On trouve facilement la bibliothèque.Bref pas de décalage tout fonctionne.Seul gros point noir, je n'ai pu commandé que par 4! Franchement c'est nul j'en voulais que une seule... Mais bon pour le prix.Je le recommande
