SparkFun Real-Time Clock Module – RV-8803

SparkFun BOB-16281 Real-Time Clock Module is a Qwiic-enabled breakout board for the RV-8803 RTC. The RV-8803 features a temperature-compensated crystal for precise timekeeping, low power consumption, and time-stamp event input. It also features a user-programmable timing offset value. The RV-8803 has an improved I²C interface that removes the need to sequence commands/writes to the device. Temperature compensation comes factory-calibrated. The Qwiic system means no soldering is required, and it has 0.1″-spaced pins if using a breadboard.
