The RTC 7 Click Board™ is a real-time clock module that has an extremely low power consumption, allowing it to be used with a single button cell battery or a supercapacitor, for an extended period of time. The MAX31341B IC built on the RTC 7 Click Board™ is able to output the time in the binary-coded decimal (BCD) format. Integrated, factory calibrated XTAL operating at 32.768 kHz ensures a very low time deviation.
However, the RTC 7 Click Board™ has the onboard external, more precise crystal oscillator too. An advanced interrupt feature allows many different uses such as alarm function, countdown timer function, external event detection function, using analogue and digital inputs and much more.
