M.2 form factor boards go mainstream in the Maker space

MicroMod from SparkFun

SparkFun has come out with a line of processors on a card called MicroMod, the idea being a different processor may be swapped into a design with few if any code changes. SparkFun has open-sourced the pinout – that step makes it easy to use the pre-made modules or to design your own board or carrier module – SparkFun.

M.2 board pinouts reference

Other manufacturers released boards prior to SparkFun in the M.2 form factor. Adafruit has developed a GitHub repo of information on various M.2 board pinouts – a very handy reference – GitHub.

Snapzz to Feather Adapter

MicroMod to Feather Adapter

Makers are looking at M.2 processors and adapting the connector to other form factors, like the Feather pinout, on Twitter here, here, and here. Nice work! Maybe a Metro/Uno form factor is next?

This may be great for CircuitPython and MicroPython, in addition to Arduino, in that the Python languages abstract out many of the hardware differences.

Learn about data science and coding with Fei from Over the Moon

Learn about data science and coding

Inspired by the new Netflix Original, “Over the Moon,” Microsoft is launching three new Microsoft Learn modules that guide learners through beginning concepts in data science, machine learning and artificial intelligence. The new Explore Space with “Over the Moon” learning path includes three parts:

  • Plan a Moon Mission using the Python Pandas Library – Like Fei Fei, use data to plan your own mission to the moon. Ensure your rocket can not only get you there, but also bring you and all your moon rocks safely back to Earth. Analyze and visualize datasets with common data cleansing practices.
  • Predict Meteor Showers using Python and VC Code – Build a machine learning prediction model after cleansing a space-themed dataset on meteor showers. Incorporate Chang’e’s potential affects on meteor showers for an added complexity.
  • Use AI to Recognize Objects in Images using Azure Custom Vision – Repurposing the camera on the lunar rover, search through the moon’s surface for Fei Fei’s buddy Bungee before it’s time to head back to Earth. Use Azure Custom Vision to classify pictures of animals without ever writing code.

Bryan

This past week, I completed the EMC2101 fan controller libraries for CircuitPython and Arduino, which means I will shortly start working on the guide. I continue to be impressed with this and other similar small, focused chips that do one or two related things and nothing else. While some may see such a chip and compare it unfavorably to another that has more bells and whistles, there is value in the flexibility that comes from having a discrete bit of functionality in its own modular piece. Sometimes you do want the flexibility of a Swiss Army Knife that can do many things, however many other times you just need a knife to cut something.

Earlier in the week I was able to assemble the latest version of the CAN Feather Wing and verify that the changes worked as expected. With any luck, this means that we should see one showing up in the Adafruit store before too long. One interesting side effect to working on this project is that I’ve started noticing CAN bus showing up in more and more places. At this point, I’m fairly sure that I’m late to the party and CAN bus has been popular for a while, however I also get the feeling that it’s seeing more and more use. I’m fairly certain that it will become even more widely known and used as more people become familiar with its benefits. As Ladyada is fond of saying, people need to use more wires. Wireless is great and all, but just like planes can be more fussy than good ‘ole trains, wires will get your bits where they need to go, even if they lack the glamour of Narrow Band IoT or Z-Wave.

Dan

I am finishing up a Learn Guide for the Blinka _bleio library. While working on the examples, I found a regression in the bleak library, which I reported and is now fixed. I have a few more examples to write and then I’ll be all done.

Jeff

I’ve been learning the ropes of ESP32-S2 development and started implementing canio. I ran into some problems that may be in the ESP-IDF, but created a workaround. The CAN hardware in the ESP32-S2 is also more limited when it comes to reception filters. In any case, the pull request is waiting for review. It will be 6.1.0 or later before it is incorporated in a stable release of CircuitPython.

Kattni

I’ve been working on a guide for a QT Py project involving NeoPixels and an LIS3DH accelerometer. It’s an activity timer that doubles as a hydration reminder. The activity timer designed to be a simple reminder to take a break every so often or eat lunch, and then get back to work. The hydration reminder counts down an interval to remind you to regularly drink water. The guide walks you through the build, and covers all the customisations available in the code. You can easily change the colors and times to fit your aesthetics and schedule. Keep an eye out for the guide soon!

Melissa

This past week, I worked on a guide for running Google Assistant on the BrainCraft HAT. Running the software on the Raspberry Pi was the easy part. The difficult part was getting all of the different Google interfaces configured correctly because halfway through, the wrong project is selected. I’m glad that I was able to work through this and document it in the guide because I think it would have been very frustrating for a user to have run into this. Voice Bonnet support will be added soon.

I also worked on another guide for creating projects using the MatrixPortal library. This goes through some of the capabilities of the library and choosing the different layers that you want to use in your project including some of the tradeoffs for choosing one method over the other. It also goes into a fairly detailed code analysis of one of the example projects that uses quite a few of the features of the library.

Scott

Last week I released 6.0.0 Release Candidate 0. I’ve done a few minor fixes after it that will lead to a second release candidate.

Most of my week has been working on adding grayscale e-paper display support to CircuitPython for the newest e-paper display FeatherWing. It’s a neat display!

I’ve got more work to do on the e-paper display because there are a few outstanding bugs. The current bug I’m looking at is that the display only refreshes once and then fails going forwards.

My goal was to work on the deep sleep API but I’ve gotten sidetracked by the new e-paper display. Both things will be done eventually though because of this top secret product ??
