Description
A power management module with RTC clock designed for the Raspberry Pi. The board is equipped with an ATtiny841 microcontroller which controls the operation of the module. The Witty Pi 4 allows scripting of power-up and power-down sequences for the minicomputer and provides up-to-date date and time without internet access and allows temperature measurement thanks to the built-in thermometer chip. It is designed to operate with a 3.7V lithium (ion or polymer) battery and can be used as an uninterruptible power supply (UPS). The module is compatible with all versions of Raspberry Pi with a 40-pin connector. It has a built-in DC-DC step-up converter. It will be used in projects that require more advanced functions to switch the device on and off depending on the supply voltage, for example.
