Hello !
I've recently purchased a Witty Pi 4 Mini to use in an underwater camera project. Basically, I've slapped the witty pi on a Raspi Zero 2, and I'm using it to wake the pi up every hour to capture a 30sec clip of the sea floor. The project is supposed to stay 2 full months underwater, and at a max depth of 200m.
What I would like to know how does the Witty pi handle a prolonged cold temperature environment, and potentially humidity too (Even though the project will be watertight, I don't know how well it'll stay this way for 2 entire months)
The project will obviously be battery powered, and I can see the documentation mentionning a DC/DC converter to be soldered on the Witty Pi, I'm still quite a novice to electronics and I have trouble picturing how to solder it, are there any examples of what converter to use or how to solder it ? I will be using 3.6V batteries and I'm wondering if I would even need the converter at all.
Thanks in advance for your responses 🙂
Small update, the answers to the temperature and humidity questions were, obviously, written in the manual... I was focused on the specifics and i didn't look at the general characteristics. My question about the DC/DC converter however, still stands unanswered
