displayio, including grayscale OLED and e-paper displays, extensive additions and improvements to BLE support, beta support for the STM32F4, iMX RT10xx and Sony Spresense microcontroller families, Korean translations, and PWM audio support. It is the first stable release for 51 boards (out of 116)! See the release notes for more details.
Thank you to all of the CircuitPython contributors and community!
Nothing is perfect, so please let us know if you find any issues. We’re looking forward to growing CircuitPython even more with follow up 5.x releases.
With the CircuitPython 5.0.0 Release Candidate 1 (released over the weekend) there are also some new boards in circuitpython.org/downloads, including:
Pyloton: Open-source CircuitPython Cycling Computer
Say hello to the open-source cycling computer that displays heart rate, speed, cadence, and song playback info (video)! Pyloton is a CircuitPython bike computer made with the CLUE board. Pyloton measures Bluetooth LE heart rate, speed, and cadence. It also provides Apple Music Service song info, combined on one small device with a sharp display and a 3D printed handlebar mount (or optional wrist mount).
This project is the culmination of three previous Adafruit Learning System projects, plus some new abilities of our Bluefruit code to connect to multiple peripheral devices! Previously, we created these standalone projects:
You may refer to those guides for additional details on the sensors, libraries, and code. Here, we’ll show you how they can all be combined into one device. Learn how to make your own open-source bike computer on learn.adafruit.com!

Metro M7 RT1011 w/AirLift WiFi. It’s not out yet…so don’t ask! It was so cold out, we stayed in and worked on the Metro M7 featuring the iMX RT1011 (the li’l sister chip to the RT1062 that stars in the Teensy 4). This chip is really fast, clocking at 500 MHz, and has 128K of RAM. For FLASH, it uses an external QSPI chip, which we’ll share for filesystem use as well. On the left, we put an ESP32 footprint, we use the ESP32 as a WiFi co-processor. You can power it over USB C or a 9V DC power jack, we’ll probably change out the 3V LDO regulator for a buck, since the current requirements are going to be high on this board. This is only 2 layers, but we think it might be OK.
CircuitSTONKS snakes its way to the NXP iMX RT1011 M7 Feather! Arturo sent us some Feather M7’s based on the fancy new RT1011 – this chip runs at 500 MHz but is only a couple US dollars each. With plenty of QSPI FLASH on board and RAM, it can make for a nice IoT engine. Here I’m using it with our ESP32 AirLift FeatherWing for WiFi connectivity and a small color TFT. The code is about 80 lines of CircuitPython – available here and YouTube.
It works on the Feather MIMXRT1011 too! – Twitter.
The NAU7802 is one of the few low-cost 24-bit ADCs, designed for bridge/strain-gauge applications. Good for precision sensor applications!
The ICM20948 is the update to the MPU-9250, we’ve done a few revisions of this tricky chip – it has a 1.8V VDDIO so there’s a lot more level-shifting required to make it 3/5V compatible! But we’re getting close… this chip is interesting in that it has a quaternion-output fusion engine built in! Hopefully this revision will be our last prototype.
Following up on Bryan’s popular DS3502 I2C digital potentiometer breakout for audio uses, we thought we’d follow up with a DS1841 digital log pot! This could be a great add-on for digitally controlled synths!

Thank you Morgan Stanley Makerspace Program for your work with Women in Need
Here’s a follow up from our story about this from last week. The Morgan Stanley Technology team recently hosted teens from Women In Need to teach them coding fundamentals using the Adafruit Circuit Playground Express. Participants created light sensors, accelerometers and more as part of the Morgan Stanley Makerspace Program. Morgan Stanley is a supporter of NYC’s largest provider of shelter and supportive housing for homeless families. Vadaparty gave us some additional information as well:
“Our family benefited from Adafruit a lot. My son grew up working on the fruits of Adafruit – from 7th grade through 12th and got into Georgia Tech (last post from high school. He taught at local STEM clubs, formulated curriculum, etc.) Seeing this success, I started a “Morgan Makerspaces” at Morgan Stanley with an intent to teach underserved communities through Morgan’s philanthropy division. What started as a small group effort grew into a large-scale success – LinkedIn. Thought all the readers and folks @adafruit would enjoy! Presently children of New York’s Women in Need shelters are receiving this education! I am personally grateful to Ladyada’s unstoppable good work! I think Adafruit’s equipment helps us all – kids of all ages, people of all backgrounds.”
Read more and on LinkedIn. Thank you so much: Kaitlyn Szydlowski, Kumar Vadaparty, Beth Reisman, Chelci Erin Houston-Burroughs, and Mimi Flynn, and everyone at Morgan Stanley for all your work with Women In Need.
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 the CircuitPython.org Contributing page. We’ve included open pull requests and issues from the libraries, 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 215!
Here’s this week’s new CircuitPython libraries:
Here’s this week’s updated CircuitPython libraries:
PyPI Download Stats!
We’ve written a special library called Adafruit Blinka that makes it possible to use CircuitPython Libraries on Raspberry Pi and other compatible single-board computers. Adafruit Blinka and all the CircuitPython libraries have been deployed to PyPI for super simple installation on Linux! Here are the top 10 CircuitPython libraries downloaded from PyPI in the last week, including the total downloads for those libraries:
What’s the team up to this week?
What is the team up to this week? Let’s check in!
Last week I managed to finish both the Arduino and CircuitPython drivers for the HTS221, as well as tester code for it to allow us to verify each and every board as they make their way from the oven to you. I also managed to write guides for both the LPS25 and HTS221. They’re both in the cue for manufacturing, so keep an eye out for them!
Next up I’m working with the ICM-20948 from invensense. This is a pretty groovy 9-DoF IMU that they describe to be “the World’s Lowest Power 9-Axis MEMS MotionTracking™ Device.” It certainly does have lots of neat features that can enable low power operation, so I’m interested to see what it’s capable of.
Over the next week, I’ll be working on libraries, tester code and likely a guide for the ICM-20948.
I finished off the last remaining blocking issues for a CircuitPython 5.0.0 general availability release, and created and released the first (well, zeroth) release candidate. So we hope to have a stable 5.0.0 release soon!
I ended up doing a lot of support over the last week, which brought me back in touch with the kinds of hardware and software issues people are currently encountering. This is helpful in figuring out what to work on next.
I’ve continued working on ulab with great ongoing support from its primary author, Zoltán Vörös. Scott also pitched in by helping us with a problem importing built-in modules whose names contain dots. There are a number of things to do before it’s ready, so we anticipate ulab will be in a 5.x.0 release, rather than in 5.0.0.
I also added support for SparkFun’s Thing Plus – SAMD51 to CircuitPython. This board has a similar microcontroller to Adafruit’s Feather M4 Express, with somewhat less storage for your Python code but a Qwiic connector—compatible with STEMMA QT products—built in. This will appear in the next beta or release candidate of CircuitPython.
This week I continued working with the Adafruit CircuitPython PyBadger library. In preparation for PyCon 2020, I was tasked with creating a simple badge example for CLUE. After deciding I wanted the option to include a preferred pronoun, it became clear what we currently had available wasn’t enough. So, I added a custom badge feature to PyBadger. It expands on the Hello-My-Name-Is-style badge to allow you to display multiple lines of text over a color-block or image background. The new feature expands the scope of what PyBadger can do significantly. With only a few lines of code, you can create a custom badge displaying whatever information you’re looking to share. The new PyBadger will be available in the CircuitPython Library Bundle this week, including examples for PyBadge, PyGamer and CLUE. I’m working on a guide page to go with it that which explains how to use all the features to make a custom badge on your Adafruit CLUE. Keep an eye out for that update!
This past week, I worked on the PulseIO implementation outside of PWMOut, which is mostly used for IR sensors. This includes PulseOut, which emulates things like TV remotes by sending a carrier signal in a defined set of pulses, and PulseIn, which interprets this information.
I also wrote a guide for getting started with the Zephyr RTOS this week. Zephyr is on everyone’s radar as an infrastructure layer that’s being used in MicroPython and may eventually be worked into CircuitPython. It was interesting to get to work with a new RTOS aside from my previous mainstay Mbed-OS, and I’m hoping to move a number of my personal projects to it in the future.
This past week I’ve been focusing on creating a Web Bluetooth dashboard that works with the Bluefruit Playground firmware on CLUE and Circuit Playground Bluefruit boards. I started off with learning Web Bluetooth and after getting the basics down, I started programming a dashboard.
This week I’ve been working on wrapping up BroadcastNet. I redid the scanning using
hcidump because the bluez interface always deduplicates advertisements from a single device. It’s been running reliably here at my house, so I’ve committed and released everything. John Park just got it running, so expect to see a guide about it soon!
I also collaborated a bit with Dan on bug squashing for the 5.0.0 release candidate. I squashed the bug where leaving a CircuitPython device with the drive ejected but USB plugged in would crash my Mac. I also fixed a safe mode crash when exiting the REPL with CTRL-D.
I’m vacationing the last half of this week in Colorado. Thursday is a bit of work day because I am visiting SparkFun and meeting up with Great Scott Gadget folks to chat about CircuitPython! The rest of the weekend is vacation.
Next week, after the regular CircuitPython Weekly, I’m going to jump into basic power savings so that
time.sleep will actually sleep the CPU. Hopefully that basic work will give a big energy savings for all of the BroadcastNet sensors and other CircuitPython boards.
The 2020 Open Hardware Summit is March 13th 2020, NYU School of Law, New York USA. The “badge” for the event is CircuitPython powered!

For International Women’s Day, on March 21st, the Lamba Labs Beirut Hackerspace will have a workshop to learn how to design, code and implement a hot potato gamified snowglobe with CircuitPython.
April 15-23, 2020, Pittsburgh, Pennsylvania, USA – The PyCon 2020 conference, which will take place in Pittsburgh, is the largest annual gathering for the community using and developing the open-source Python programming language. It is produced and underwritten by the Python Software Foundation, the 501(c)(3) nonprofit organization dedicated to advancing and promoting Python. Through PyCon, the PSF advances its mission of growing the international community of Python programmers – PyCon 2020.
Speaking of events, as of right now we do not know which ones will be canceled or postponed due to COVID-19. That said, there is no time like the present to use technology to bring people together… Adafruit has been doing a form of live video “Show and Tell” for about 10 years or so, every single week. We started with Google Hangouts, and after that was sunsetted by Google, we moved to StreamYard and it’s fantastic. The video above is from our Show and Tell from last week. We have some of our team show what they’re up to and anyone around the world can join in and show and share their latest project. We’ve hired about a dozen people from meeting them via our Show and Tell. We’ve seen kids grow up before our eyes over a decade, we’ll made friends, a community together. We’ve had folks stream from hospital beds to makerspaces to girl scout troops.
Here’s the playlist on YouTube, there are about 400 videos … and check out StreamYard. We have nothing to do with them other than using their service. We stream the Show and Tell each week to: YouTube, Facebook, Twitch, Mixer, LinkedIn, and Periscope. The text chat is in our Discord, with about 16,000 members: https://discord.gg/adafruit
If you have a company or community (or both!), try it out, and if you make “something”, anything, (everyone does!), stop by and join us Wednesdays at 7:30pm US Eastern Time.
