Absolute Native Electronics DS3231 AT24C32 IIC Precision RTC Real Time Clock Memory Module

الوصف

DS3231 is a 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. Size: 38mm (length) * 22mm (W) * 14mm (height) Operating voltage :3.3 - 5 .5 V clock chip: high-precision clock chip DS3231 Clock Accuracy :0-40 Degree range, the accuracy 2ppm, the error was about 1 minute Calendar alarm clock with two Programmable square-wave output Real time clock generator seconds, minutes, hours, day, date, month and year timing and provide valid until the year 2100 leap year compensation Chip temperature sensor comes with an accuracy of ± 3 Degree Memory chips: AT24C32 (storage capacity 32K) IIC bus interface, the maximum transmission speed of 400KHz (working voltage of 5V) Can be cascaded with other IIC device, 24C32 can be shorted A0/A1/A2 modify default address is 0x57 Wiring instructions (with Arduino uno r3 for example): SCL A5 SDA A4 VCC 5V GND .
