CircuitPython takes flight – Using CircuitPython on High Altitude Balloons
Matt’s team is using CircuitPython for on high altitude balloons! Their team HABET (High Altitude Balloon Experiments in Technology) is part of a program called Make 2 Innovate. Make To Innovate (M:2:I) is an exciting program in the Department of Aerospace Engineering at Iowa State University which engages students in hands-on projects to augment their understanding of engineering fundamentals – Make to Innovate (M:2:I) Department of Aerospace Engineering at Iowa State University.
Why choose CircuitPython? Matt writes –
“We had been programming it in C up until this launch, but with myself graduating next semester, along with the Computer Engineer on our team, we needed to find a way to allow for ease of maintenance. When I found you guys had libs for the radio and GPS we decided to try that out. The radio portion worked fantastic.”
ALL ABOARD’ CircuitPython.org updates – datum!
The goal of the datum project is to make it easier for students and hobbyists to incorporate sensors into their projects by doing the heavy lifting of translating the language the sensors speak into a format that’s easy for humans to read and for machines to parse and process.
Towards that end, each datum board emulates a serial port over a USB connection, presenting the information and data stored on them in a JSON encapsulated packet, and processes URI style commands to change and retrieve their settings. The datum boards fill the gap between a LEGO® Mindstorms® sensor and a breakout board.
And now, the datum boards support CircuitPython! Check them all out on CircuitPython.org!
By the numbers: CircuitPython has over 66+ boards supported, adding more each week & has 16+ SBC Linux boards supported, adding more each day, & over 164+ Libraries, adding more every week!
Testing the Circuit Playground Express Bluefruit

TEARDOWN 2019: Supercharge Your Hardware Old and New with CircuitPython by Scott Shawcroft
TEARDOWN 2019 video is now posted! Supercharge Your Hardware Old and New with CircuitPython by Scott Shawcroft – YouTube & slides.
“CircuitPython makes programming hardware easier than ever by bringing the popular Python language to modern, inexpensive 32-bit microcontrollers. This doesn’t need to be limited to modern hardware though. By pairing a modern microcontroller running CircuitPython and a vintage computer, such as a GameBoy or Yamaha piano keyboard, you can unlock the unique characteristics of these vintage devices. In this talk, you’ll learn the basics of how CircuitPython makes coding easy, how it works under the hood, and how to extend CircuitPython with C. As an example, we’ll supercharge a Nintendo GameBoy with CircuitPython. By the end of the talk, you’ll be able to supercharge your own hardware project with CircuitPython.”

Design Evolution of the Programmable USB Hub
The CircuitPython-supported Programmable USB Hub design evolution article is up on Crowd Supply!
“Today’s update is going to be a dive into the design progression and evolution of the Programmable USB Hub. Note, I didn’t start out with the aim of creating a product which smashes together a USB Hub, Power Supply, Development Board, and IO expander – my aim was simply to create a product which provided more monitoring and control of USB devices.”

Why Mu? Mu tries to make it as easy as possible to get started with programming but aims to help you graduate to “real” development tools soon after. Everything in Mu is the “real thing” but presented in as simple and obvious way possible. It’s like the toddling stage in learning to walk: you’re finding your feet and once you’re confident, you should move on and explore! Put simply, Mu aims to foster autonomy.

Call for help – CircuitPython messaging to other languages!
We posted on the Adafruit blog about bringing CircuitPython messaging to other languages, one of the exciting features of CircuitPython 4.x is translated control and error messages. Native language messages will help non-native English speakers understand what is happening in CircuitPython even though the Python keywords and APIs will still be in English. If you would like to help, please post to the main issue on GitHub and join us on Discord.
We made this graphic with translated text, we could use your help with that to make sure we got the text right, please check out the text in the image – if there is anything we did not get correct, please let us know. Dan sent me this handy site too.
jobs.adafruit.com has returned and folks are posting their skills (including CircuitPython) and companies are looking for talented makers to join their companies – from Digi-Key, to Hackaday, Microcenter, Raspberry Pi and more.

Codecademy “Learn Hardware Programming with CircuitPython”
Codecademy, an online interactive learning platform used by more than 45 million people, has teamed up with the leading manufacturer in STEAM electronics, Adafruit Industries, to create a coding course, “Learn Hardware Programming with CircuitPython”. The course is now available in the Codecademy catalog.
Python is a highly versatile, easy to learn programming language that a wide range of people, from visual effects artists in Hollywood to mission control at NASA, use to quickly solve problems. But you don’t need to be a rocket scientist to accomplish amazing things with it. This new course introduces programmers to Python by way of a microcontroller — CircuitPython — which is a Python-based programming language optimized for use on hardware.
CircuitPython’s hardware-ready design makes it easier than ever to program a variety of single-board computers, and this course gets you from no experience to working prototype faster than ever before. Codecademy’s interactive learning environment, combined with Adafruit’s highly rated Circuit Playground Express, present aspiring hardware hackers with a never-before-seen opportunity to learn hardware programming seamlessly online.
Whether for those who are new to programming, or for those who want to expand their skill set to include physical computing, this course will have students getting familiar with Python and creating incredible projects along the way. By the end, students will have built their own bike lights, drum machine, and even a moisture detector that can tell when it’s time to water a plant.
Visit Codecademy to access the Learn Hardware Programming with CircuitPython course and Adafruit to purchase a Circuit Playground Express.
Codecademy has helped more than 45 million people around the world upgrade their careers with technology skills. The company’s online interactive learning platform is widely recognized for providing an accessible, flexible, and engaging experience for beginners and experienced programmers alike. Codecademy has raised a total of $43 million from investors including Union Square Ventures, Kleiner Perkins, Index Ventures, Thrive Capital, Naspers, Yuri Milner and Richard Branson, most recently raising its $30 million Series C in July 2016.
