Better Alternative

[ShakingMocha]

I'm on a project that uses MLX90640 thermal sensor but my MEGA has insufficient memory.can someone suggest a better and stronger alternative that is compatible with arduino and can handle the sensor?

The Grand Central would be a good upgrade. It has the same footprint as the Mega, but with an ATSAMD51 - M4 processor. That gives you 1MB flash and 256 KB RAM. Plus a lot more processing power - including floating point capability which will speed things up considerably with the MLX90640 images.
