RTC Battery Kit Real Time Clock Holder (Not include CR2032 Battery) for Raspberry Pi 5

Specification

(CR2032 Battery Not Included)

The RTC (Real-Time Clock) Battery Kit is designed to provide continuous timekeeping functionality to the Raspberry Pi 5, even when power is disconnected. It includes a battery holder and connection cable, enabling the Raspberry Pi to maintain date and time across reboots and power losses. Ideal for headless systems, data loggers, or remote applications without internet access.
