More info


The RTC real-time clock module enables precise and independent measurement of time from the work of other systems. The built-in supercapacitor enables the clock to be powered up during power outage. The module contains a PCF8563 (NXP Semiconductors *) chip with an I2C interface and the ability to generate 32.768 kHz, 1.024 kHz, 32 Hz or 1 Hz signals. The configuration jumper V_SEL +3,3 V / + 5 V enables selection of supply voltage and digital signals.


The standard setting of the power jumper is +3.3 V.
