New DS3231 AT24C32 IIC Precision RTC Real Time Clock Memory Module ZS-042 For Arduino

NOTE: Battery not included! 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 improve 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. RTC maintains seconds, minutes, hours, day, date, month, and year information. Le than 31 days of the month, the end date will be automatically adjusted, including corrections for leap year. The clock operates in either the 24 hours or band / AM / PM indication of the 12-hour format. Provides two configurable alarm clock and a calendar can be set to a square wave output. Addre and data are transferred serially through an I2C bidirectional bus. A precision temperature-compensated voltage reference and comparator circuit monitors the status of VCC to detect power fais, provide a reset output, and if neceary, automatically switch to the backup power supply. In addition, / RST pin is monitored as generating μP reset manually. Save time and high precision addition, DS3231 also has some other features that extend the system host of additional features and a range of options. The device integrates a very precise digital temperature r, through the I2C * interface to acce it (as the same time). This temperature r accuracy is ± 3 ° C. On-ch power supply control circuit can automatically detect and manage the main and standby power (i.e., low-voltage battery) to switch between the power supply. If the main power fai, the device can continue to provide accurate timing and temperature, performance is not affected. When the main power re-power or voltage value returns to within the allowable range, the on-ch reset function can be used to restart the system microproceor. Specifications: Size: 38mm (length) * 22mm (W) * 14mm (height) Weight: 8g Operating voltage :3.3 - 5 .5 V Clock ch: high-precision clock ch DS3231 Clock Accuracy :0-40 ° range, the accuracy 2ppm, the error was about 1 minute Calendar alarm clock with two Programmable square-wave output Real time clock seconds, minutes, hours, day, date, month and year timing and provide valid until the year 2100 leap year compensation Ch temperature r comes with an accuracy of ± 3 ° memory chs: AT24C32 (storage capacity 32K) IIC bus interface, the maximum transmiion speed of 400KHz (working voltage of 5V) Can be cascaded with other IIC device, 24C32 addrees can be shorted A0/A1/A2 modify default addre is 0x57 With LIR2032, to ensure the system after power fai, the clock move any natural normal Packing: single anti-static pack Wiring instructions (for Arduino uno r3 for example): SCL → A5 SDA → A4 VCC → 5V GND → GND Package Included: 1 x DS3231 module a (tested good antistatic pack)
