STEMMA SUNDAY – MLX90640 Thermal Camera @adafruit @sparkfun @seeedstudio @dfrobotcn #qwiic #grove #gravity #stemma #stemmaQT

This weekend we worked up making a Stemma QT (qwiic/Grove compatible) breakout for the MLX90640 32×24 camera (video). We’ve got it working nicely in Arduino up to about 8 fps (you need a fast processor like the SAMD51 with lots o RAM). Then we went back to our old AMG88xx thermal cam demo and ported it to our EdgeBadge. This camera could be good for low cost thermal imaging and also machine learning!

Adafruit STEMMA & STEMMA QT Plug & play connectivity

WHAT IS STEMMA? STEMMA is not an original idea, we’re working within an ecosystem of many other plug and play systems. We started STEMMA in 2014, and intended to be compatible with Grove only (cause that’s all that existed at the time) but then when Qwiic came around in 2017, added a smaller connector so we could work with those parts too!

STEMMA attempts to be as cross-compatible as possible with both Grove and Gravity (compatible connectors & 3-5V power/logic). STEMMA QT is cross-compatible with Qwiic - STEMMA QT connector/cable is same as Qwiic. You can use STEMMA QT devices with Qwiic devices/controllers.

More STEMMA & STEMMA Sunday! – Adafruit.


As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
