&gt; What microcontrollers you have in mind? He mentioned Arduino in the post. It&#x27;s not like we need Dart for extremely low spec-ed mCs<p>The article mentions the Arduino, which in its original incarnation is an extremely tiny AVR. Maybe the author has a more powerful Arduino variant in mind, but I&#x27;m pretty sure you cannot run a GC runtime on the AVR Arduino. The only language that runs on such tiny devices  is probably eLua.<p>&gt; , and we could run GC just fine in higher level mCs for ages...<p>Yes, RPi&#x2F;BBB won&#x27;t have a problem.
