This item is perfect for the project i am building. The project in question is a time lapse of the sky overnight to photograph meteors,satellites,aircraft. using the RPI4B and a RPI camera v3 wide noir and software designed for this type of interest. The Witty Pi 4 allows accurate time keeping which is important and is very versatile with many ways to handle the Power Management. Downloading the software and installing was easy . I would highly recommend downloading the excellent user manual . I have set the project up to use a schedule script. Which can be tested or created to your requirements on the witty web site generator. You can access the settings via the web page or on a mobile phone. Or using the command line in ssh. The build quility is excellent and the witty pi4 is a well thought out quality product. I highly recommend this item.
