Precision RTC Module for Raspberry Pi Pico (DS3231)

This is a high-precision RTC expansion module specifically designed for the Raspberry Pi Pico. The module incorporates a high-precision DS3231 RTC chip and uses the I2C bus for communication. The stackable design allows you to add other hardware whilst using the RTC board. Note: Raspberry Pi Pico not included. You'll need a Pico with male headers soldered to it. You can grab a Pico here and Pico male headers here, or buy a Pico with pre-soldered headers. Features

* Standard Raspberry Pi Pico header, supports Raspberry Pi Pico series

* Onboard high precision RTC chip DS3231, with backup battery holder

* Real-Time Clock Counts Seconds, Minutes, Hours, Date of the Month, Month, Day of the Week, and Year with Leap-Year Compensation Valid Up to 2100

* Optional format: 24-hour OR 12-hour with an AM/PM indicator

* 2x programable alarm clock

* Online development resources and manual (Raspberry Pi Pico C/C++ and MicroPython examples)

* Dimensions: 52mm x 21mm
