PyPortal – A new Python-powered board
We’re starting to collect some of the demo projects for PyPortal, our upcoming easy-to-use IoT device that allows you to create all the things for the “Internet of Things” in minutes. Make custom touch screen interface GUIs, all open-source, and Python-powered, that uses tinyJSON / APIs to get news, stock, weather, cat photos, and more – all over Wi-Fi with the latest technologies. Create little pocket universes of joy that connect to something good. Rotate it 90 degrees, it’s a web-connected conference badge #badgelife.
This playlist contains some of the recent videos from our beta/demo testing.
The PyPortal uses an ATMEL (Microchip) ATSAMD51J20 and an Espressif ESP32 Wi-Fi coprocessor with TLS/SSL support built-in. PyPortal has a 3.2″ 320 x 240 color TFT with resistive touch screen. PyPortal includes: speaker, light sensor, temperature sensor, NeoPixel, microSD card slot, 8MB flash, plug-in ports for I2C and 2 analog/digital pins. There are 3D files for custom enclosures and lanyard fastening. PyPortal is Open Source hardware, and Open Source software, programmable in CircuitPython and Arduino. The device shows up as a USB drive and the Python code can be edited in any text editor.

Python Discord, now with #microcontrollers channel
There are even more reasons and resources to learn Python, and/or join one of the largest coding communities in the world – check out Python Discord –
“Python Discord is the official Discord server of r/Python on Reddit (326k subscribers). We’re a large, friendly community focused around the Python programming language, open to those who wish to learn the language or improve their skills, as well as those looking to help others. We organise regular community events and have a dedicated staff of talented Python developers available to assist around the clock. Whether you’re looking to learn the language or working on a complex project, we’ve got someone who can help you if you get stuck.”
Python Discord now has a #microcontrollers channel! Join in https://discord.gg/djuFYQA for the largest Python community and now with hardware too!
Python snakes its way to a new robotics board for Raspberry Pi
The Robotics Masters MM1 HAT is an open source robotics controller board for Raspberry Pi. It removes the initial barriers to starting any robotics project by providing all the hardware you need in an easy to use form factor. The board has compatibility with many open source software libraries such as CircuitPython and SeeSaw – MM1 HAT, Crowd Supply.

In December 1990, an application called WorldWideWeb was developed on a NeXT machine at the European Organization for Nuclear Research (known as CERN) just outside of Geneva. This program – WorldWideWeb — is the antecedent of most of what we consider or know of as “the web” today.
In February 2019, in celebration of the thirtieth anniversary of the development of WorldWideWeb, a group of developers and designers convened at CERN to rebuild the original browser within a contemporary browser, allowing users around the world to experience the rather humble origins of this transformative technology.

New Learn Guides!
Updated Guides – Now With More Python!
You can use CircuitPython libraries on Raspberry Pi! We’re updating all of our CircuitPython guides to show how to wire up sensors to your Raspberry Pi, and load the necessary CircuitPython libraries to get going using them with Python. We’ll be including the updates here so you can easily keep track of which sensors are ready to go. Check it out!
Keep checking back for more updated guides!
CircuitPython support for hardware continues to grow. We are adding support for new sensors and breakouts all the time, as well as improving on the drivers we already have. As we add more libraries and update current ones, you can keep up with all the changes right here!
For the latest drivers, download the Adafruit CircuitPython Library Bundle.
If you’d like to contribute, CircuitPython libraries are a great place to start. Have an idea for a new driver? File an issue on CircuitPython! Interested in helping with current libraries? Check out this GitHub issue on CircuitPython for an overview of the State of the CircuitPython Libraries, updated each week. We’ve included open issues from the library issue lists, and details about repo-level issues that need to be addressed. We have a guide on contributing to CircuitPython with Git and Github if you need help getting started. You can also find us in the #circuitpython channel on the Adafruit Discord. Feel free to contact Kattni (@kattni) with any questions.
You can check out this list of all the CircuitPython libraries and drivers available.
The current number of CircuitPython libraries is 133!

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.
