The Raspberry Pi single board computers (SBCs for short) are normally used with the Raspberry Pi OS. This is great for gaming and web browsing, but isn’t designed for microcontroller-like tasks. Tasks like reading I2C sensors and SPI devices can be trickier. Furthermore, Linux system maintenance can be tricky for beginners.
Instead of Raspberry Pi OS, one can now use CircuitPython instead. CircuitPython running without another operating system (OS) is typically known as “bare metal”. This greatly simplifies system maintenance and makes it easier to treat the Raspberry Pi like a microcontroller. In addition, running CircuitPython on the Raspberry Pi increases the amount of flash and RAM available to CircuitPython programs. Finally, it also adds the ability to use displayio on HDMI displays.
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.
