樹莓派 Raspberry Pi 高精度High Accuracy 配件 RTC 時鐘模塊 (DS3231) (103030278)
Description
The High Accuracy Pi RTC is based on the clock chip DS3231, the DS3231 is a low-cost, extremely accurate I2C realtime clock (RTC). It can provide a real-time clock(RTC) for raspberry pi via the I2C interface. With the clock source from the TCXO(temperaturecompensated crystal oscillator), the RTC provides seconds, minutes, hours, day, date, month, and year information. The date at the end of the month is automatically adjusted for months with fewer than 31 days, including corrections for leap year.The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator.
The clock provides two programmable time-of-day alarms and a programmable square-wave output. The INT/SQW pin either generates an interrupt due to alarm condition or outputs a square-wave signal and the selection is controlled by the bit INTCN.
If you want to keep this module timing when the Raspberry Pi is powered off, you need to put a 3-Volt CR1225 lithium cell in the battery-holder.
Note : The battery is not included.
注意 : 電池不包括在內。

Pin Out
注意
1-芯片本身支持報警功能，我們還保留了相關的硬件接口，但我們的軟件庫不包含此功能（S / INT引腳），需要進行相關的軟件開發。
2-RX / TX未在此模塊中使用，但6x2接頭佔用了Raspberry Pi的RX / TX引腳，因此我們將RX / TX輸出並帶有2pin接頭。
