AstroLink 4 Pi is the first device in the AstroLink family, that can operate in standalone mode. It is controlled by the internal Raspberry Pi* 4 module, which is responsible for running the astroimaging setup. Provided AstroLink 4 Pi INDI driver controls all the device components. Recommended operating system is astroberry (https://www.astroberry.io/) with KStars and Ekos software (see Ekos documentation here).
AstroLink 4 Pi is powered with 12V via a reliable XT60 socket. It can either connect to an existing WiFi network or create its own hotspot. Once connected, an imaging session can be planned via a remote desktop available in the regular browser. Any computer, laptop, or tablet can be used to plan and control the imaging session. See the astroberry system page and AstroLink 4 Pi manual for details.
