The entire thing is waterproof and probably weighs 3 or 4 lbs. It probably wouldn’t make you super popular with airport security, but the whole thing is portable. I’ve got a 16gb SD card for the main operating system and a 16gb flash drive for extra storage. It can boot into Raspbian and features wifi so you can ftp into it if wanted. Unfortunately there is no way to externally power the system while you are using it, but they are beefy lipo batteries that should hold out for several hours.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
