Feature

●【DS3231】 DS3231 is a cost-effective, extremely accurate I2C real-time clock (RTC) with built-in temperature compensated quartz oscillator (TCXO) and quartz. The device has a battery input, disconnects the main power supply and ensures accurate time keeping. The integrated oscillator improves the long-term accuracy of the device and reduces the number of components in the production line. The DS3231 is available in commercial and industrial temperature ranges
●【Compact Design】 Size: 38mm (Length) * 22mm (W) * 14mm (H) Weight: 8g; Operating Voltage: 3.3-5.5V; Clock Transmitter Chip: High Accurate Clock Engine DS3231; Clock Accuracy: Range 0-40, Accuracy 2ppm, Error Approx. 1 minute;
●Compatibility: calendar alarm clock with two, programmable rectangular output, real time clock generator seconds, minutes, hours, day, date, month and year that are valid until the year 2100 as leap year. The chip temperature sensor has an accuracy of ± 3; memory modules: AT24C32 (capacity 32 K);
●【High Performance】 IIC bus interface, maximum transmission speed of 400kHz (working voltage of 5V); can be cascaded with other IIC devices, 24C32 addresses can be short-circuited. A0 / A1 / A2 change the default address is 0x57; with the CR2032 rechargeable battery, the device can normalize the natural movement after a power failure. Packaging: Single Anti-Static Packaging
●Fast delivery: Fast and high quality delivery from Spain when buying TECNOIOT


Description

DS3231 AT24C32 IIC Module Precision Clock Module DS3231SN x2

Description:

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, disconnect the main power supply and maintains accurate timekeeping. Integrated oscillator improves long-term accuracy of the device and reduces the number of components of the production line. The DS3231 is available in commercial and industrial temperature ranges, using a 16-pin 300mil SO package.
