DS3231 Real Time Clock Module for Raspberry Pi

โมดูลนาฬิกา Real Time Clock ใช้ไอซีเบอร์ DS3231 มีเซนเซอร์อุณหภูมิในตัว พร้อมแบตเตอร์รี่

The DS3231 is a low-cost, extremely accurate I2C real- time clock (RTC) with an integrated temperature- compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input, and maintains accu- rate timekeeping when main power to the device is inter- rupted. The integration of the crystal resonator enhances the long-term accuracy of the device as well as reduces the piece-part count in a manufacturing line. The DS3231 is available in commercial and industrial temperature ranges, and is offered in a 16-pin, 300-mil SO package.
