The Landa Tianrui Precision Clock Module is a compact RTC (Real-Time Clock) board designed for microcontroller projects, compatible with Arduino and Raspberry Pi systems.
In practical use, this module helps maintain accurate time in applications like data logging, IoT devices, or environmental monitoring, even in varying temperatures, by providing a stable clock source without needing additional power converters.
- Timing accuracy of +/-5ppm within -40°C to +85°C, ensuring reliable performance in diverse conditions.
- Battery backup for uninterrupted operation during power loss.
- Supports 3.3V and 5V systems directly, with full clock functions including alarms and a digital temperature sensor.
- Low-power consumption and high-speed I2C interface for easy integration.
- Reset button and outputs like 1Hz and 32.768kHz for flexible project needs.
With dimensions of 2.2 cm x 1.2 cm x 0.5 cm and a black PCB material, it's a lightweight (5g) option for hobbyists and engineers seeking precise timing solutions in compact designs.
