I have purchased a Raspberry Pi 3 B+. I have a question about powering this and other electronics in an outside, waterproof, ventilated junction box, similar to:
http://www.altelix.com/14x12x8-Vented-Universal-NEMA-Enclosure-100-240VAC-p/nf141208vau.htm
In addition to the Raspberry Pi, the box will contain a RTL2832U RTL-SDR dongle, a Low Noise Amplifier (LNA) for the 21 cm 1420MHz hydrogen line and two 5V cooling fans. The RTL-SDR is connected to a USB port on the Pi, and the LNA connected to the other end of the RTL-SDR.
The LNA requires 8v to 12 v at 150mA. Probably 9v would be OK to keep the temp down.
Ethernet 6A cable to the Pi will be sending raw data from the dish back to the computer in the house.
What would anyone recommend for powering this setup with a single power source, distribution and use of say, UBEC DC-DC converters?
Would this be possible to do as POE to Pi (e,.g. through the Pi POE hat/daughter board and then distribution to the other devices? For the LNA, I imagine a boost converter from Pi to 9v would be the way to go?
Looking for specific solutions please.
Thanks,
Peter
