High Precision Real Time Clock Module DS3234 Arduino Keyestudio

The DS3234 Module is an affordable, high-precision SPI™ real-time clock module with an integrated temperature-compensated crystal oscillator. The DS3234 features accurate temperature- and voltage-compensated circuitry that will compare and monitor VCC.

This low-power module allows you to count multiple time units, such as seconds, minutes, hours, days, months and even years. In addition, this module has up to 2 daily alarms.

If the power supply is interrupted, this device switches its power supply to the backup input in order to maintain an accurate and stable time count.

On the other hand, crystal integration allows the module to increase its long-term accuracy, while reducing the number of parts needed to develop the DS3234.

The high-precision real-time clock module is designed for use in a temperature range between -40ºC and 85ºC, and fits into a 300K, 20-pin market-standard package.
