DWM-DS3231 is high precision Real Time Clock Module For Arduinowhich equipped with integrated TCXO and crystal.
DS3231 is equipped with integrated TCXO and crystal, which makes it a cost-effective I2C real time clock with high precision. The device carries a battery input, so if you disconnect the main power supply, it can still maintain accurate timing. The integrated oscillator ensure the long-term accuracy of the device and reduce the number of components. DS3231 provides both commercial and industrial temperature range and supports 16 Lead Small Outline Package (300mil). The module itself can adapt to the system of 3.3V and 5V without level switch and is super convenient!
