Description

Module with a real time clock (RTC) system RV-1805. The circuit has a very low current consumption (up to 22 nA) and has two built-in oscillators: 32.768 kHz quartz and an RC oscillator, which is adjusted every few minutes for better accuracy. The element supporting the operation of the module is a supercapacitor that provides up to 35 days of work without power supply and, unlike batteries, can be recharged. In the event that the user needs backup for a longer time, he can additionally connect a battery with a larger capacity. Communication with the module takes place via the I2C interface. There are two Qwiic connectors on the board. On the product page, there is also a user manual and an Arduino library.
