Many Hams have abandoned including a Raspberry Pi in their field Go-Kits.
There are a couple of reasons for this:
1) Pi’s are expensive relative to other options.
2) Pi’s have a reputation for being power hungry and running hot.
3) Pi’s run on 5V making them a pain to power in a 12V Ham world.
I am still a fanboy of the Pi for EmComm use. Why?
First, they are small and reliable. Second, they are also extremely flexible since they run a version of the Debian Linux OS. Finally, since they run on 5V DC, it is easy to keep them powered for very long stretches of time.
I solved the Pi field power problem with one of these:
This is step-down transformer that converts an input of 10-32V DC to a clean 5V. Plus each USB port provides up to 3A. Perfect for a Pi. You can buy two of these devices on Amazon for less than $20.
All you need to do is terminate the ends with PowerPole or XT-60 connectors and you are good to go.
These are not only great for a Pi, you can use them to power/ charge any mobile device that runs on 5V.
