The smôl RTC is a smôl-format board for the RV-8803 Real Time Clock. The RV-8803 boasts some impressive features including a temperature compensated crystal providing extremely precise time-keeping, low power consumption, and time stamp event input along with a user-programmable timing offset value. The RV-8803 also has an improved I2C interface compared to the RV-1805 RTC that removes the need to sequence commands/writes to the device. Best of all, the temperature compensation comes factory calibrated. The RV-8803's INTerrupt pin can be connected to the smôl bus via configurable jumpers. The smôl RTC provides access to the RV-8803's EVI pin too via a breakout pad.
Adding a real-time clock to your project is the perfect way to get more accurate data; timing or otherwise. The RTC module has counters for hundredths of seconds, seconds, minutes, hours, date, month, year and weekday with a number of alarm and interrupt settings available as well. Plus the large operating temperature range of the RV-8803 and temperature compensated crystal makes it a good addition for field applications or harsh environments.
