What means "m"?

Some reports available.

• "Em"beddable.

• "M"atz.

Can I run mruby on my target?

Arduino

Basically, No.

On the current version of mruby, it is not enough considered to support 16-bits integer architectures. And AVR have small size of RAMs. (NOTE: AVR is MPU that used in Arduino.)

But you can run mruby on some Arduino-pin-compatible boards. Like chipKIT Max32, GR-SAKURA, Enzi, and so on. They boards have high spec 32bits CPUs.

I recommend compatible boards if your wish is using Arduino shields.
