Yeah a Pi is a completely terrible solution for something like this because it doesn't really play to any of its strengths. Android phones are cheaper, more reliable, have a built in battery, touchscreen, GPS and compass (so you can navigate with one too), and have you know... actual power management so you don't run out of said battery. Sometimes they're even dust and waterproof which is probably good in a tropical rainforest or a sandy desert.

Where do you get Android phones for cheaper than a Raspberry Pi (e.g. $35 for a Pi 4)?

> $35 for a Pi 4

Lol, if you have them at that price I'll take 5. More like $80-120 at current market rates, and then you still need to buy everything else that's already included in a phone.

I’m so tired of people citing $35 for a Pi. Maybe for a Pi Zero (non W). But $120 is standard at this point.

Second hand market? Samsung, OnePlus, HTC, LG, Nexus, Nokia, Pixels, with quad core CPUs and RAM >2GB can be had dirt cheap depending where you live.

Choose a popular, old flagship that's well supported by the community, and can be flashed with a de-Googled ROM and you're gold.

Old OnePlus devices are still supported today by the community.
