Witty Pi 3 Rev2 - power module with RTC DS3231 clock for Raspberry Pi

Description

The power supply module with the RTC DS3231SN clock is designed for the Raspberry Pi. The board is equipped with an ATtiny841 microcontroller and a Step-Down MP4462 converter, which allows the minicomputer to be powered with a voltage of up to 28 V and the creation of scripts for the switching on of the minicomputer. The module is compatible with all versions of the Raspberry Pi with a 40-pin connector. It will be used in projects that require more advanced functions of switching the device on and off depending, for example, on the supply voltage. Full documentation with examples is available in the GitHub repository.
