?, Overview:

Raspberry Pi foreign highest precision clock module DS3231

Note that the Arduino motherboard also uses this module.

The module itself can adapt to 3.3V and 5V systems, without level conversion, which is super convenient!

?, Features:

1. Within the temperature range of -40°C to +85°C, the timing accuracy is maintained at ±5ppm(±0.432 seconds/day).

2. Provide battery backup for continuous timing

3. Low power consumption

4. Device package and function are compatible with DS3231

5. Full clock calendar features seconds, minutes, hours, weeks, dates, months, and years with leap year compensation valid through 2100

6. Two calendar alarm clocks

7.1Hz and 32.768kHz output

8. Reset output and button to shake input

9. High-speed (400kHz)I2C serial bus

10.+2.3V to +5.5V supply voltage

11. Digital temperature sensor with accuracy of ±3°C

12. Operating temperature range from -40°C to +85°C

13.16 Pin SO(300mil) package

?,.Module test This module adopts IIC test method, so it only needs to connect D on the module to Arduino A4, C to A5, + to VCC, and – to GND, as shown in the figure below:
