Selectable accuracy: choose between the RX8025T and DS1302 realtime clock chips to match your accuracy and drift requirements for automotive clocks and other timekeeping applications. Spacesaving form factor: compact 40 x 13 mm size fits into tight dashboard openings, instrument clusters, or compact electronic enclosures without major redesign. Multifunction display: the module provides advanced features including measurement and voltage monitoring so you can view essential vehicle or device data alongside time information. Easy time and date management: set and adjust hours, minutes, and date quickly through the module's controls for straightforward operation and maintenance. Adaptive visibility: builtin automatic brightness control adjusts the display to changing ambient light, improving daytime readability and reducing glare at night. Automotiveready integration: designed for use in vehicles and other electronic devices where reliable timekeeping, compact size, and clear readouts matter. Practical applications Dashboard retrofit: install as a compact clock and monitoring readout in car or truck dashboards where space is limited and visibility in varying light conditions is required. Custom instrument clusters and DIY electronics: integrates into hobby or professional projects that need selectable RTC accuracy, time/date adjustment, and voltage/measurement display without a large footprint. Portable or embedded devices: suitable for compact electronic products that require reliable timekeeping, onscreen measurement information, and automatic brightness control. What makes it stand out Choice of two proven RTC chips (RX8025T or DS1302) for flexible accuracy and performance. Very small footprint (40 x 13 mm) for easy integration into constrained spaces. Combines timekeeping with measurement and voltage monitoring and adaptive brightness for practical, everyday use in vehicles and electronic devices.
