Designed by me, the Astroberry power supply delivers 84 W of power, which is enough even when I connect additional devices to all four USB ports that are powered from those ports. The power supply’s output voltage is the standard 12 VDC.
The Raspberry Pi 4, which is the “heart” of Astroberry, is normally powered with 5 VDC. My own Astroberry design is powered by 12 VDC via an appropriate voltage converter; I’ll skip further details for now — that’s a topic for a separate article on my website, which is slowly taking shape. Its compact size allows me to take it anywhere.
I can and do use the built power supply to power any astrophotography rig. For almost a year it has worked very well every time I use it. So far it has never let me down.
