DS3231 I2C RTC Module khusus DS3231M

Tentang produk :

DS3231 adalah module real-time clock (RTC) yang murah dan sangat akurat. Dilengkapi dengan integrated temperature-compensated crystal oscillator (TCXO) dan kristal.

Dengan adanya baterai, waktu yang sudah disetting tetap akan terjaga.

Sudah termasuk baterai ya kak.
