Other people are doing this with 12 Volt LNAs, so need a higher voltage battery and solar panel setup, plus a voltage converter to get it down to 5V AND a solar panel controller that will do 12V. Having said that most of the higher rated panels use 12V, so I would need to go this route if I can’t find a 5V panel of a decent rating. | Other people are doing this with 12 Volt LNAs, so need a higher voltage battery and solar panel setup, plus a voltage converter to get it down to 5V AND a solar panel controller that will do 12V.

The current limit on the RPi shouldn’t be an issue hopefully, as I’ve used them off battery with a few gadgets like RTL sticks in before. | + | Hopefully I just mount the PiJuice HAT, connect the battery and panel setup, and hopefully it’ll produce enough juice.

If there are any issues with current I may need a powered USB hub, which adds complexity and potential RFI sources. I would also like to know if there’s an alternative to the rather expensive PiJuice for all of this. | If there are any issues with current I may need a powered USB hub, which adds complexity and potential RFI sources.

On the non-RF side it’ll be a RPi 3B or 4, depending on what’s available. A 3B will do it just fine if I can still get them and will run cooler, but Pis are *very* sold out. I’ll maybe need a WiFi dongle with an external antenna socket to try and reach the long range to my living room router (this is a stretch goal really). | On the non-RF side it’ll be a RPi 3B or 4, depending on what’s available.
