The DS3231 real-time clock module offers precise timekeeping for electronic projects and devices.
In scenarios like IoT setups, data loggers, or alarm systems, it maintains accurate timing and temperature monitoring, even during power interruptions, helping ensure reliable operation without constant power.
- High-precision DS3231 chip with 2ppm accuracy, resulting in about 1 minute annual error under normal conditions
- Built-in temperature sensor accurate to +/- 3°C for environmental monitoring
- I2C bus interface supporting up to 400KHz for fast, easy integration with microcontrollers like Arduino
- Rechargeable LIR2032 battery for backup power, keeping the clock running when main power is off
- 32K memory (AT24C32) for storing additional data
- Compact size of 38mm x 22mm x 14mm and lightweight at 8g, suitable for space-constrained designs
This module is ideal for hobbyists, students, and engineers working on projects that need dependable real-time clocks with added functionality.
