This distribution can boot on 486DX PC with 24 MB of ram (did not boot with less using QEMU). On an emulator it boots almost instantly. On bare metal modern hardware, the only thing that prevent those speeds is the actual speed of a floppy drive.
I’m using the latest revision. It’s a feat of it’s own that connects old and new technologies together. At the moment it is Kernel 5.13.0-rc2.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
