Description
- Operating voltage: 3.3 – 5 .5 V
- The module com4 clock chip: high-precision clock chip DS3231 5 Clock Accuracy :0-40 ° range, the accuracy 2ppm, the error was about 1 minute 6 calendar alarm clock with two 7 programmable square-wave outputes fully assembled
- 8 Real time clock generator seconds, minutes, hours, day, date, month and year timing and provide valid until the year 2100 leap year compensation 9 chip temperature sensor comes with an accuracy of ± 3 ° 10 memory chips: AT24C32 (storage capacity 32K)
- DS1307 based RTC without11.IIC bus interface, the maximum transmission speed of 400KHz (working voltage of 5V) 12 can be cascaded with other IIC device, 24C32 addresses can be shorted A0/A1/A2 modify default address is 0x57 13 with rechargeable battery LIR2032, to ensure the system after power failure, the clock move any natural normal LIR2032 battery
- 14 Packing: single anti-static packaging Wiring instructions (for Arduino uno r3 for example): SCL → A5 SDA → A4 VCC → 5V GND → GND
