@jbz Not sure how I feel about this - - I'm guessing the move is to the AI side because the Arduino app is supporting all the off brand clones.
My guess is that they will stop development on the "traditional" low end Arduino board support and focus instead on the Qualcomm chip side, and use MicroPython support for the STM32.
Now, Broadcom should consider supporting the #micropython project if they don't already, and also look at #pybricks for how to do a web app that lets you write Python code or make a block based programs ...
