ChronoDot V3 High Precision RTC _MAKE_SENSOR_ENVIRO This SHARP distance sensor bouncesThe ChronoDot RTC is an accurate real time clock module, based on the MAX31328 temperature compensated RTC (TCXO). It includes a CR1632 battery which should last at least 8 years if the I2C interface is only used while the device has 5V power available. No external crystal or tuning capacitors are required. The MAX31328 has an internal crystal and a switched bank of tuning capacitors. The temperature of the crystal is continuously monitored, and the
