I know, so far, that they can be used to flash with Biscuit firmware to make wardriving nodes, among other things. But what could I use one inside a uConsole for?
Use it for the same things you’d use it out side for. I’ve use one with the diy biscuit firmware and the biscuit manager app on Waydroid with gps fed over gpsd. Right now I’m running vord on it for a skimmer dector.
