Product description
Pico-RTC-DS3231 provides Raspberry Pi Pico with a high-precision real-time clock (RTC). The module uses the DS3231, a temperature-compensated RTC IC, enabling accurate timekeeping even over long periods without frequent synchronization.
Communication is handled via I2C, allowing easy integration into both new and existing projects. The stackable design makes it possible to combine the module with other expansion boards without consuming additional connections.
The module is equipped with a backup battery holder (CR1220), ensuring that time and date are maintained during power loss. The RTC handles seconds, minutes, hours, date, day of the week, month, and year, including leap year compensation up to the year 2100. It also supports both 12-hour and 24-hour formats, as well as two programmable alarm functions.
The design is adapted for direct mounting on Raspberry Pi Pico via pin headers. Support is available for both C/C++ and MicroPython, and example code is provided for quick implementation.
