Welcome to our space 🌍
We are electronic engineers focused on carrying out electronic developments, where they can be applied in favor of technology, the designs, modules and schemes can be used freely to be incorporated in their automation developments applied to the Internet of Things where it is based on interconnection digital of any product or object with any other around using the internet.
We have different Modules that can be used in electronic designs, implementations, prototypes and validations such as regulated sources, rtc, sd, ethernet, lora, lorawan among others, these can be applied to devices such as stm32, Arduino Uno, Mega, Esp32 , Esp8266.

Questions
How big is the Ds3231 PCB?
It measures 38 × 28.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ds3231 use?
18 parts, built around the AT24CS32-SSHM-T, DS3231MZ+ and 1N4148W. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Ds3231 KiCad files?
From the risejohan/2Bit repository on GitHub, at the commit this page was made from: the board is module RTC/ds3231/ds3231.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ds3231 design in my own project?
Its repository states no licence, so its author keeps all rights: ask risejohan before reusing the design.
