Sure doesn't take up much space. About as compact as it can get. If you need the INT/SQW pin, which is not connected on this module, you will need to connect a jumper wire from pin 3 to the unused NC pin of the Dupont connector. That way you can use the alarm features on the chip...

Because this RTC module works at 3.3 V there is no risk of damaging the Pi with 5 V to the I2C pins. Furthermore, pin order is perfect to connect to the board. Some instructions could be given in the product page, but they are easily found online. From powering down the Raspberry pi, inserting the RTC board, rebooting and making the necessary changes in /etc/rc.local, etc., it took under 5 minutes. Now I don't have to worry about power failures making a mess of the fake hardware clock tehe Pi uses.

جاء بدون بطارية، لكنه يعمل مع أي بطارية خلية 3v. من الجيد أن توت العليق غير متصل بالشبكات للحصول على ساعة.

Came without battery, but it works with any 3v cell battery. Nice for raspberry that aren't connected to networks to get hour.

Really small and super easy to setup. Just add: dtoverlay=i2c-rtc,ds1307 to /boot/config.txt and it works.

Very nice, small and compact. It does it's job well and includes a temperature sensor even with the small size

Works good and the batteries seems fresh

Easy to install on the RPI, just placed if on the header pin (see photo) put power back on and check what it shows up on the I2C bus (address 68) with: sudo i2cdetect Add this command at startup of the RPI in order to adjust the system time from the RTC: sudo hwclock -s

Good RTC. battery status of all RTC good. (here are many problems by others). Also the PBC has right lenght in the area of the connector. So the RTC can be placed beside other connector on the GPIO board on the R-PI

مرحباً لقد تلقيت طلبي اليوم لكني لم أجربه بعد شكراً لك

bonjour j'ai bien reçu ma commande aujourd'hui mais je ne l'ai pas encore essayé merci

Reloj DS3231 El packaging del producto es SENSACIONAL, muy buena la presentación, nada que reclamar. Actualmente estoy en el proceso de "aprendizaje", razón por la cual no puedo decirles más. ____________________________________________________________________________ Llegó el paquete tengo que probar su correcto funcionamiento.
