Works fine at 3.3V, runs a little slow. GND pins work.
This is a great DS1307 RTC with 4kB EEPROM that I mated with an ESP-WROOM-32 to create a recording voltmeter. Works as expected. The clock on mine runs about 12ppm slow (-1 sec/day) which I compensate in software.The DS1307 is designed for 5V but runs fine at 3.3V due to the backup battery having a voltage divider that lowers the power fail trip point. The divider runs down the battery faster than without it. The EEPROM works fine. Originally, I tried a DS3231 RTC with (purported) internal crystal, but the generic version had erratic accuracy, losing one hour every ten hours. The beauty of the DS1307 is that the 32.768 kHz crystal is external and can be verified.This assembly appears to be a clone of the Gizmo TinyRTC I2C Module.By the way, the GND pins are connected to the ground plane on the back side and to appropriate circuit points. The PCBs I received were not defective and did not require modification.

Es lo que esperaba
El producto llegó tal cual en la foto, su empaque lo protegió durante el camino y no pude esperar más o menos. Recomendado.

They run slow
I haven't yet compensated for it in software like was suggested by another review, but will look into that.

A lot of time passed and PCB still nto fixed
You may have read that some time ago people reported the PCB connection error that needs to be corrected by wiring ground using a piece of wire. Well, that is still the case. Depending on your application the low price and need for immediate repair may be appealing or not.

Good
As described- Not sure what I'll do with 5 of them lol
