Technical specifications indicate the DreamSky Digital Alarm Clock utilizes a dedicated CMOS timekeeping IC with an integrated crystal oscillator, achieving an accuracy of approximately +/- 1 second per month. The display architecture features 2-inch LED segments paired with a wide-angle polarizing filter for high-contrast visibility. A physical rheostat provides 0-100% linear dimming, allowing for complete elimination of light output during sleep cycles.
The unit requires a 5V DC input for operation, with a secondary USB-A port providing a 5W power output for low-draw peripherals. A 2x AAA battery compartment provides power for memory retention only. Standardized testing confirms the absence of firmware or network-based protocols, ensuring operational stability during internet outages or server failures.
This device is a reliable peripheral within smart clock displays, providing a simplified tactile interface for primary timekeeping.
To integrate this standalone clock into a broader automation routine, consider using it alongside Echo Show 5, which can trigger synchronized room lighting and alarms through network commands.
