There are many reasons to encrypt the root file system on the Raspberry Pi, from keeping WiFi credentials immutable to keeping proprietary software and sensitive data from being cloned. For many Raspberry Pi configurations, only two partitions exist:
/boot on /dev/mmcblk0p1
/ on /dev/mmcblk0p2
So it makes sense to encrypt the root partition as a way of encrypting everything.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
