All about the product
Raspberry Pi Pico expansion module in the form of a real-time clock (RTC). With a high-precision chip DS3231, it uses the I2C bus to interact with the Raspberry Pi Pico. Its design allows for the addition of multiple peripheral devices that connect to each other. The board has an additional holder for CR1220 coin batteries. The RTC clock counts seconds, minutes, hours, days, months, and years, with leap year compensation valid until 2100. Time is displayed in two formats: 24-hour or 12-hour with AM/PM indicator. Additionally, it has two programmable alarms.
