Raspberry Pi high-precision clock module DS3231
Note Arduino board can also use this module.
Module itself can adapt to 3.3V and 5V systems without level conversion, this is a super easy!
۱. -۴۰ [deg.] C to +85 [deg.] C in the temperature range, timing accuracy is maintained at ± ۵ppm ( ± ۰.۴۳۲ Miao / day )
۲. The continuous timing Battery Backup
۳. Low power consumption
۴. The device packaging and functionality DS3231 compatible
۵. The complete calendar clock functions include seconds, minutes, hours, day, date, month and year time, and provide valid until 2100 year leap year compensation
۶. The two-day alarms
۷. The 1Hz and 32.768kHz output
۸. Reset button to output and input jitter
۹. High-speed (400kHz)I2C serial bus
۱۰. The + 2.3V to + 5.5V supply voltage
۱۱. The accuracy of ± ۳ [deg.] C Digital Temperature Sensor
۱۲. The -40 [deg.] C to +85 [deg.] C operating temperature range
۱۳. A 16 -pin SO(300mil) package
