SparkFun Real Time Clock Module - RV-8803 (Qwiic)

The SparkFun RV-8803 Real Time Clock Module is a high-precision, Qwiic-enabled breakout board for the RV-8803 RTC. This module is packed with remarkable features such as a temperature-compensated crystal for precise time-keeping, low power consumption, and a time stamp event input with a user-programmable timing offset value. The RV-8803 offers an improved I²C interface over the RV-1805 RTC, eliminating the need to sequence commands/writes to the device. The temperature compensation feature comes factory calibrated, ensuring accuracy right out of the box. The module is compatible with the Qwiic system, making it easy to connect to your system without soldering. Additionally, 2.54mm-spaced pins are available for breadboard use.

The SparkFun RV-8803 is an excellent addition to any project that requires accurate data and timing. It can be easily incorporated into your project through the Qwiic connector. The module includes counters for hundredths of seconds, seconds, minutes, hours, date, month, year, and weekday. It also offers a wide range of alarm and interrupt settings. With its broad operating temperature range (-40 to +105°C) and temperature-compensated crystal, this module is a reliable choice for field applications or harsh environments.

The SparkFun Qwiic Connect System is an ecosystem of I²C sensors, actuators, shields, and cables designed to make prototyping faster and less error-prone. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector, which saves PCB space and ensures correct connections.

The package includes one SparkFun Real Time Clock Module - RV-8803 and one 12mm CR1225 Coin Cell Battery.

Key features of the SparkFun RV-8803 include factory-calibrated temperature compensation, high time accuracy, 1.5V to 5.5V operating voltage range, low-power consumption, I²C address: 0x32, periodic countdown timer interrupt function, periodic time update interrupt function, alarm interrupts for weekday or date, hour and minute settings, external event input with interrupt and time stamp function, programmable clock output pin for peripheral devices, operating temperature range: -40 to +105°C, and 2x Qwiic Connectors.
