I am always worried when I bring development boards on airplanes. I assume most people are reasonable, but I worry for a few that might not be.

I brought a 5G Peplink modem (which has 4 external antennas) in my checked luggage and got "randomly searched" by TSA on both legs of a trip once, which I thought was pretty hilarious.

I used to travel with a case full of parts for work and just started leaving extra zipties inside because the TSA agents that would search it wouldn't always ziptie it back closed after they were done.

I've brought mini clusters of bare Pis many times before (and other strange contraptions with jumper wires all around), and the only time I was ever stopped for a deeper search was when I left my x-ray shielding bag for film in the same case with the mini cluster.
