Hello Community
I'm a total newbie and so forgive me for asking something that maybe is clearly impossible or super trivial..
with the new model of the Raspberry PI Zero, the W model, with built-in Wi-Fi and Bluetooth, would it be possible to "easily" add a tactile button on the side of the case to turn on/off this connectivity? And hook it on some of the GPIO pins of the RP.. or something like that
Because that would be neat.. since I ordered it for my GBZ build

Thank you!

Should be doable by reading GPIO state and short script using "sudo ifconfig wlan0 down". Might need to reboot to bring wifi back up though. I'm sure a better command might be found without the reboot but that would be the gist of it.
