[rascani]

Create an example application for Arduino (resource-constrained target).

• Working example on Arduino Uno Q (MCU) or similar Arduino board
• Fits within Uno Q flash/RAM constraints
• Documents model size and memory requirements

Nice choise, both a Cortex-A 4GB Ram/32GB Flash for larger models and to run/test XNNPACK and a Cortex-M33 with 786 KB SRAM/2MB flash for embeded tests. Seem to have Zephyr support so Cortex-M stuff will probably be easy to get working and probaly XNNPack also in Linux mode (and kind of easy for Zephyr also if needed). Maybe I accedently ordered one, who knows :)
