What's smaller than a Feather but larger than a Trinket? It's an Adafruit ItsyBitsy M4 Express featuring the Microchip ATSAMD51! Small, powerful, with a ultra fast ATSAMD51 Cortex M4 processor running at 120 MHz - this microcontroller board is perfect when you want something very compact, with a ton of horsepower and a bunch of pins. This Itsy is like a bullet train, with it's 120MHz Cortex M4 with floating point support and 512KB Flash and 192KB RAM. Your code will zig and zag and zoom, and with a bunch of extra peripherals for support, this will for sure be your favorite new chipset.
This guide will get you up and running with Adafruit IO - the easiest way to get your project on the web. Learn what hardware is compatible with IO, how to interact with your data, troubleshooting your IO project, available client libraries, and about taking your project to the next-level with IO Plus.
Mu is an amazing editor that works with CircuitPython and compatible boards. You can connect to the serial REPL right inside the editor. It also includes a plotter the works with your code to give you a live visual graph of your data! This guide will show you different ways to use the plotter with different sensors. It's time to plot!
New to CircuitPython? Looking for an easy way to get started? We've written a library for the Circuit Playground Express that makes it super simple to begin using all the sensors, switches and lights. This guide will show you all the features of this library and how to use each one. Let's get coding!
This guide will use the capacitive touch pads on the Circuit Playground Express and the capacitive properties of fruit to create a full scale tone piano. We will write the code using CircuitPython to use each of the touch pads to light up the Neopixels in a different color and play a different tone through the onboard speaker.
ItsyBitsy M0 Express is only 1.4" long by 0.7" wide, but has 6 power pins, 23 digital GPIO pins (12 of which can be analog in, 1x analog out, and 13x PWM out). It's the same chip as the Arduino Zero and packs much of the same capability as an Adafruit Metro M0 Express or Feather M0 Express but really really small. So it's great once you've finished up a prototype on a Metro M0 or Feather M0, and want to make the project much smaller. It even comes with 2MB of SPI Flash built in, for data logging, file storage, or CircuitPython code.
The pIRkey adds an IR remote receiver to any computer, laptop, tablet...any computer or device with a USB port that can use a keyboard. This little board slides into any USB A port, and shows up as an every-day USB keyboard. The onboard ATSAMD21 microcontroller listens for IR remote signals and converts them to keypresses, mouse movements, or even USB serial output.
New from the fine people who have brought us the Beagle Board, we now have a smaller, lighter, but powerful single board linux computer, Beagle Bone! We like this move to a more compact and integrated SBC. For example, there is onboard Ethernet and USB host, as well as a USB client interface (a FTDI chip for shell access). It even comes preloaded with Angstrom Linux on the 4 GB microSD card! Here are some tips and tricks to get your BeagleBone up and running.
Use the CRICKIT board with your Circuit Playground Express to control a cardboard animatroinc hand. Four servo motors pull the fingers into position using cable drive systems made from cord and straw guides. Program it all with CircuitPython to actuate as you press the capacitive touch controllers. You'll also learn to use the CRICKIT as an audio-animatronic controller with pre-programmed sounds and motions, such as counting in binary!
