Lightweight device to read and record from Seek Thermal Camera?

Wow.  What galaxy style phone is that?  (saves me from trial & error).
You know you can run android on a raspberry pi 4...

Perhaps even something easily compatible with lightweight wireless transmission module for real-time video feed to the ground?

A Lepton FS + the DroneThermal board would fit that bill.

I'm going with a 9 gram raspberry pi zero W (python opencv) + 15g seek pro (320 pixels).  Then I can pop the shell off my mavic mini (26g) and still be under the 250g weight "limit".

Haven't checked this thread in a while, sorry about that.

Long story short: I switched to raspberry PI zero (Version 2 with wifi). All things considered, it proved more practical for the task.
Initial tests worked fine-ish. Namely, the camera was working on the drone and all, but there were a few practical problems:
- without a custom mount, camera plugged into the board directly was facing downwards, making it rather impractical (effective FOV when facing downwards is the smallest).
- custom mount increased usb cable length (or, rather, introduced it), and that, surprisingly, made communication with seek thermal unstable
- raspberry PI zero being of top of the drone (where it's easy to mount) interfered with GPS signal reception on the drone itself (making it rather unwise to fly it long distance like that), while sitting at the bottom has other issues (there are sensors at the bottom). Plus, wifi signal from the PI was interfering with signal from the drone in general,  reducing it's effective range.
- once the snow fell, field tests were put on pause until spring

Good tip on the gps interference.  I'm curious what library you ended up using for the seek<>pi?
