Particle deprecates Particle Mesh, discontinuing Particle Xenon

Particle has announced today that they are discontinuing development of Particle Mesh, their OpenThread-based mesh networking solution, and will no longer be manufacturing their associated Xenon development board.

Particle states they ran into two barriers which kept them from delivering on the promise with Particle Mesh:

  • Mesh networking, while a compelling technology, is extremely complex, and trying to make it “just work” with zero configuration for all customers in all environments just wasn’t feasible. As a result, the experience of Particle Mesh doesn’t live up to the standard that we set for ourselves with our other products.
  • It turns out that, for most of our customers, 802.15.4 mesh networking seems to not have been the right technology in the first place; most customers would be better off using Bluetooth Low Energy (which we will continue to invest in) or a sub-GHz radio like LoRa (which can be added to Particle through third-party accessories).

See Particle’s full announcement and learn How to use Xenon with CircuitPython.

Testing CircuitPython on Teensy 4.0 – IoT made easy IoTeensy

CircuitPython has landed on the NXP iMX RT1062. We threw together a quick IoT project which uses the AirLift FeatherWing to fetch inspirational quotes from Adafruit’s quote service and displays them on an OLED FeatherWing. – Adafruit Blog

The World’s First LoRa SoC: STM32WL

STMicroelectronics announced the launch of the STM32L, the world’s first integrated LoRa System-on-a-Chip (SoC). This is the first silicon which integrates a microcontroller and a sub-GHz radio, previously two separate modules. – CNX Software

Arduino Portenta H7

Arduino released a new Pro line at CES 2020 with a new flagship board – the Portenta H7. This board contains a STM32H747, Murata 1DX dual WiFi 802.11b/g/n 65 Mbps and Bluetooth 5.1 BR/EDR/LE, Secure Element (NXP SE0502), and a GPU (Chrom-ART graphical hardware Accelerator).

Use-cases for this $99 board include “high-end industrial machinery, labratory equipement, computer vision”, and machine learning. – Arduino.cc

WeMos W600-PICO

WeMos released a new board for $2.10 USD plus shipping. The CPU is a Winner Micro W600 ARM Cortex-M3 WiSoC and the board is pre-loaded with MicroPython. – CNX Software

Adafruit IoT Updates

All the Internet of Things Episode 6: Digi-Key IoT Studio

Adafruit and Digi-Key have teamed up to present All the Internet of Things – a six-episode series covering everything you could ever want to know about the Internet of Things.

We are very excited to release the final episode, which incorporates all the different subjects discussed in previous episodes, and shows off this incredible resource: Digi-Key IoT Studio.

Unlike most other IoT platforms, Digi-Key IoT Studio is code-less — all sensor interaction and storage is done automatically by the drag-and-drop IDE. You don’t need to install toolchains, code editors or compile any code on your computer! Digi-Key Studio runs in your web browser, handles all aspects of developing an internet of things project, and even compiles your code remotely.

Watch the full video or check out this guide to get started now.

We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
