I know the basics of code but want to dive deeper. Which device is better to start learning on?
Since I own both, I gotta say: go for the Cardputer! 
It’s way more affordable to start with. Plus, it pairs perfectly with AI—you can easily use Gemini to help you generate code and learn the ropes, which makes getting started super smooth. Flashing it via Arduino IDE is a breeze, too. It’s an awesome device to learn on!
Cardputer, absolutely! Looks cooler with keyboard. More functional too.
