Arduino Ventuno Q

The $299 introductory price is not bad at all; for comparison, a Raspberry Pi 5 with 16GB RAM runs you ~$350 (Adafruit). And this Ventuno Q includes 40TOPS that the Pi doesn't come with by default, the Pi AI HAT+ 2 costs another ~$220 (Cyton.io).
So $299 vs $570, and the Arduino also has 4 more cores.
Arduino doesn't know who they are anymore.
