Module parameters:
1. Size :38mm(length)*22mm(width)*14mm(height)
2. Weight: 8 g
3. Working voltage: 3.3-5.5v
4. Clock chip: high precision clock chip DS3231
5. The clock precision: 0-40 range, precision 2 PPM, in error about 1 minute
Bring 2 calendar alarm clocks
7. Programmable square wave output
8. Real-time clocks generate seconds, minutes, hours, weeks, dates, months and years, and provide intercalary year compensation up to the year 2100
9. The chip itself temperature sensor, the accuracy of plus or minus 3
10. Memory chip :AT24C32(storage capacity is 32K)
11.IIC bus interface, with maximum transmission speed of 400KHz(when working voltage is 5V)
12. Other IIC devices can be cascaded. The 24C32 address can be modified by short circuit A0/A1/A2, and the default address is 0x57
13. The battery CR2032 ensures that the clock will still move normally when the system is powered down
14. Packing method: single anti-static packing
Wiring instructions (take Arduino uno r3 as an example):
SCL - A5
The SDA - A4
The VCC - 5 v
GND to GND
