Julian Y. ★★★★★

Barely bigger than a coin, yet it's got both the DS1307 clock and that 2KB AT24C32 EEPROM tucked in—my datalogger finally keeps time across power cycles without extra wiring. The backup battery holder is a lifesaver for a beginner like me.

Grace S. ★★★★★

Plugged it into my Arduino and the I2C address was exactly as documented, so no hunting through datasheets. The on-board AT24C32 EEPROM is a nice bonus, letting me stash calibration data without wasting the DS1307's timekeeping registers. Timekeeping's been spot-on after a day of testing.

Mia C. ★★★★★

Barely bigger than a postage stamp, yet it handles both timekeeping and that 32K EEPROM over I2C without a hiccup. Soldered it into a data logger and the AT24C32 side is already proving perfect for storing calibration values.
