It took me forever but I finally got around to picking up a Flipper Zero. I have a ESP32 GPS and CC1101 Board on the way as well - for educational purposes of course. I’ve managed to get the Flipper setup with Flipper Xtreme firmware and play with it a bit. So far, I haven’t been disappointed. The amount of depth in this device, especially when enhanced with custom firmware, is insane. It can open up a near limitless number of rabbit holes for you to go down if you can find the time.
If you’re interested, Exploiting the Tangible: Hands-On Pentesting Techniques with Flipper Zero, is a pretty good overview of its capabilities (and responsible use).
