we still have screens on our windows...).</font><br>

within the scope of FCC rules and FAA rules on drone

rtl-tcp. It is light enough that RPi0 nas enough
computational power to handle it. The SBC on the drone
needs to be connected via WiFi to your ground station,
so adding an external antenna connector may be
necessary. I did that on Pi0, and it wasn't too scary.
IIRC you need to move one capacitor (this can be
tricky, it's an 0402-ish part), and an MMCX connector
which you mount on the footprint on the board.</div>
