Keep time in an embedded project with the RV-1805 on this Qwiic RTC board. Its low-power operating modes allow using a supercapacitor as backup, and I2C carries communication to the host. Additional 0.1-inch pins offer another connection option, providing a timekeeping component for projects that need to preserve clock operation across interruptions.
