The Arduino 101 is simple. It’s a board that combines the universal appeak of Arduino with the latest technologies – like the Intel Curie module, Bluetooth LE capabilities, and a 6-axis accelerometer/gyro.
The Arduino 101 contains two tiny cores, an x86(Quark), and a 32-bit ARC architecture core, both clocked at 32MHz. The board also comes with 14 digital input/output pins (4 can be used as PWM outputs), 6 analog inputs, a USB connector for serial communication and sketch upload, a power jack, an ICSP header with SPI signals and 12C dedicated pins. The board’s operating volate and I/O is 3.3V but all pins are protected against 5V overvoltage.
The Arduino 101 is very new, and uses a completely new core chipset! Many libraries won’t work with it, it’s currently recommended for makers & engineers who want to try out the latest and greatest!
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.
