i.MX6 Carriers RTC Overview

General Information


A real-time clock (RTC) is a computer clock that keeps track of the current time. The RTC circuitry is integrated into the HummingBoard Professional and the Cubox-i uses a CR1620 sized Lithium/Manganese Dioxide (LiMnO²) Coin Cell.

This coin cell should be the only part to connect to the header provided on the device to power this circuit.
