DFRobot (DFR0641) MEMS Precise RTC Module, Fermion, Arduino Board

Product Information Accessory Type: MEMS Precise RTC Module For Use With: Arduino Board Product Range: - Product Overview DFR0641 is a Fermion: DS3231M MEMS Precise RTC (Breakout). This MEMS precise RTC breakout board adopts DS3231M chip, which integrates MEMS resonator and temperature compensator. Compared to quartz crystal clock, the real-time clock reduces the risk of mechanical failure. Therefore, it can be used in a highly vibrating environment. Within -45°C to +85°C, the accuracy of the DS3231M is ±5ppm (±0.432 s/D). High anti-vibration Internal MEMS resonator and temperature compensator Clock calendar 2 programmable calendar alarms Operating voltage range from 3.3V to 5.5V Dimension is 22.5 x 21mm / 0.886 x 0.827inch
