Features:
The module is a real -time I2C (RTC) real -cost clock with high precision with crystalline oscillator compensated at integrated temperature (TCXO) and crystal.
The device includes a battery entrance door that maintains accurate timing when the network supply is disconnected. The integrated crystalline oscillator improves the long -term accuracy of the device.
Both commercial and industrial temperature intervals are provided, adopting a 300 MIL 16 PIN package.
This product is made with high quality ABS material, strong and.
This clock module also has other functions that extend the range of functionality and additional options' host of.
