This is a reliable, battery-backed real-time clock (RTC) designed to keep track of time for your microcontroller project, even during power loss or reprogramming. Ideal for applications such as data logging, clock building, time-stamping, timers, alarms, and more, it features the PCF8523 RTC, which can operate with both 3.3V and 5V power and logic.
Key Features:
-
PCF8523 RTC: Simple, low-cost RTC that keeps accurate time with minimal power consumption. It may lose or gain up to 2 seconds per day, making it a great option for general timekeeping tasks.
-
Compatibility: Works seamlessly with Arduino (via RTC library), CircuitPython, and Raspberry Pi (or other similar single-board computers).
-
Battery-Backed: Maintains time even if power is lost, perfect for long-term projects.
-
Convenient Design: The board includes headers and plugs directly into any breadboard. You can also use wires for easy connection.
-
Durability: The RTC can keep accurate time for over 5 years when powered by a CR1220 coin cell battery (not included).
-
Mounting Holes: Two mounting holes make it easy to integrate into your project.
Please note, this product does not come with the CR1220 coin cell battery, but one can be easily purchased separately. If you're looking for a high-precision, temperature-compensated alternative, consider the DS3231 RTC. For those needing compatibility with older projects, the DS1307 RTC breakout is also available.
