Description
Description:
A DS1302 RTC (Real-Time Clock) Module is a small, low-power device for microcontrollers (like Arduino) that keeps accurate time (seconds, minutes, hours, date, year) even when the main power is off, thanks to a backup battery, using a 3-wire serial interface (CLK, DAT, RST) for simple communication. It features a 32.768 kHz crystal for precision and includes 31 bytes of battery-backed SRAM for data storage, making it ideal for projects needing persistent timekeeping.Specifications:
- DS1302 Chip: The core integrated circuit that manages time and calendar functions.
- 32.768 kHz Crystal: Provides the precise frequency for accurate timekeeping, as shown in this YouTube video.
- Battery Backup: Usually a CR2032 coin cell, allowing time to be maintained when the Arduino loses power.
- 31 Bytes SRAM: Battery-backed static RAM for storing user data.
- Three-Wire Interface: Simplified communication using CE (Chip Enable), I/O (Data), and SCLK (Serial Clock) pins.
- Voltage Compatibility: Works with both 3.3V and 5V systems.
