The real-time clock expansion board for Raspberry Pi is an expansion board for adding a real-time clock (RTC) function to the Raspberry Pi (hereafter referred to as Raspberry Pi).
Provides accurate time to the Raspberry Pi even in a standalone environment without a network. It uses an RTC DS3231 with a built-in high-precision crystal oscillator, and it uses a coin battery on the board to keep the time even when the Raspberry Pi is turned off.
In addition to the RTC function, it is also equipped with an OLED display, external connector, piezoelectric buzzer, switch, LED, etc., and can be used for various purposes.

Product features

Highly accurate RTC function with DS3231

A temperature-compensated crystal oscillator (TCXO) is built in to provide highly accurate time.

Using a coin battery on the board, it can keep accurate time even when the Raspberry Pi is powered off.

Abundant functions that can be linked with RTC
