Adafruit IOT Monthly: MQTT Comes to CircuitPython, an Interactive IoT Airplane Sculpture and more!
Adafruit IOT Updates
MQTT comes to CircuitPython!
So, you have a CircuitPython project and want to connect it to the internet? You may want to consider adding MQTT to your project. MQTT is an extremely popular and lightweight protocol which can connect your project to the internet and quickly process network events. We’ve built a robust MQTT module for CircuitPython called CircuitPython MiniMQTT to quickly get you started connecting your projects to the internet and sending data around. Learn all about using MQTT with CircuitPython in on the Adafruit Learning System Guide here!
Adafruit IO CircuitPython Library UPDATE: MQTT!
The Adafruit IO CircuitPython library has been updated with a new IO_MQTT class for accessing Adafruit IO’s MQTT Broker. We’ve included helpful methods for simplifying interactions with Adafruit IO over MQTT. Download the latest version of the Adafruit IO CircuitPython Library in the CircuitPython Bundle here and check out some examples which make use of the new MQTT class here.New IoT Hardware: 8-Channel LoRa Gateway HAT with LoRa and GPS Antenna
This LoRa HAT from RAK Wireless is capable of multi-channel, multi-node communication, all running in a non-intimidating, hackable Raspberry Pi environment. Unlike our basic LoRa gateway bonnet, this chipset can support all 8 channels, so it can handle multiple clients, on different LoRa channels, without having to do any code tweaks. Visit the product page fo the LoRa Gateway HAT here! Once you have your Internet-to-LoRa gateway set up with this kit, make LoRa nodes using our Feather line for easy deployment of sensor networks that run on battery power. We have guides about setting up LoRaWAN nodes using either Arduino OR CircuitPython on the Adafruit Learning System here.#ComingSoon IoT Hardware: Circuit Playground Express BlueFruit
We are testing the Circuit Playground Express BlueFruit, check out the coming soon photos. We went to Washington Square Park at night to test how far we could change the colors of the NeoPixels on the CPX Bluefruit and we’re going to need a bigger park to test in maybe 🙂
Watch us test the CPX BlueFruit here!!

Interactive Airplane Sculpture, beautiful and internet connected
“The Imagination Machine” has been my main focus for a little over 9 months. I’m thrilled to see it in such a grand space. As you may read in the articles, it tracks the ISS using the NASA open API + Adafruit.io + IFTTT. It keeps time using the RTC. It also has some other codes onboard that I’m developing that will use more of NASA’s API (tracking near earth orbit asteroids, etc.) I had always intended for the piece to make a connection from country to country as well. At the moment, I’m currently on an artist residency in Dresden, Germany. It’s ongoing exploration includes allowing my new friends here in Germany to say “Hello” to the sculpture in Ohio from my phone. Using using the Adafruit.io and my phone, they can trigger a special light show that connects two different cultures located an ocean apart - Adafruit BlogIssue 21 HackSpace magazine: Air quality monitor

Adafruit IO Plus Plan Upgrades Are Here!
One of the most consistent requests we’ve had since we launched IO Plus (IO+) was for a way to raise the IO+ account limits even further.
Library Update: Adafruit IO Arduino
If you have a shiny new piece of Adafruit WiFi AirLift hardware and want to use it with Arduino - you’re in luck! The Adafruit IO Arduino library has been updated to v3.1.0, including an update for using AirLift boards (such as the PyPortal or Metro M4 WiFi Lite) or breakouts.
Grab the new release from the Arduino Library Manager or download it from the Adafruit GitHub.
New IOT Hardware from Adafruit
Adafruit’s new WiFi boards have arrived. Both of these boards come with AirLift - our witty name for the ESP32 co-processor - and are compatible with both Arduino and CircuitPython. All AirLift boards can also connect to Adafruit IO.
Adafruit AirLift – ESP32 WiFi Co-Processor Breakout Board
Give your plain ol’ microcontroller project a lift with the Adafruit AirLift - a breakout board that lets you use the powerful ESP32 as a WiFi co-processor. You probably have your favorite microcontroller (like the ATmega328 or ATSAMD51), awesome peripherals and lots of libraries. But it doesn’t have WiFi built in! So lets give that chip a best friend, the ESP32. This chip can handle all the heavy lifting of connecting to a WiFi network and transferring data from a site, even if it’s using the latest TLS/SSL encryption (it has the needed root certificates pre-burned in). This breakout includes a crypto chip, too!
Want to pick one up? Visit the Adafruit Store!
Adafruit Metro M4 Express AirLift (WiFi) - Lite
Give your next project a lift with AirLift - our witty name for the ESP32 co-processor that graces this Metro M4. You already know about the Adafruit Metro M4 featuring the Microchip ATSAMD51, with it’s 120MHz Cortex M4 with floating point support. With a train-load of FLASH and RAM, your code will be fast and roomy. And what better way to improve it than to add wireless? Now cooked in directly on board, you get a certified WiFi module that can handle all your TLS and socket needs, it even has root certificates pre-loaded. Since this is a lite version of the AirLift module, it has a 8MB flash and no crpyto chip.
