A me too board that's too late .
In my view Arduino have
lost their ways a long time ago.
Too much
hardware diversification at stupidly high prices and exponentially increasing complexity. Platform instability doesn't inspire confidence to beginner developers.
People who want
Linux have the Pi , in 2 form factors, the regular and the compute module. These have a guaranteed life cycle so you can design a product around the board knowing that it is available 5 years into the future, even after new generation products are released.
People who want lower prices and don't care about guaranteed availability 3 years into the future have a multitude of choices, bananapi, orangepi , nanopi etc.
The entry level low end of this market has been eaten by stuff like ESP32 and Uno rev 3 clones
sold at below 10% of genuine Uno prices.
These newer Arduino sbc's with development kits costing more than Nvidia Jetson devkits make no senso to me.
I've seen similar ideas in the past, for example I have a LattePanda V1 of about 10 years ago that combined a Windows and Linux sbc with an Arduino in a board about the same size as a raspi.
2 years into the
project my clients decided to switch to a Raspberry Pi.
