What is true of it
A5 is A and E — 1 and 5 counted from A.
The easiest of the 5 fingerings below is 2400: 2 fingers, held at the 2nd fret.
None of them uses an open string, so this chord moves up the neck unchanged — the same shape 1 fret higher is the chord a semitone above.
Where its notes are on the neck
The brass dots are A, the root. Everything else is a chord tone with its degree printed in it.
With a different note underneath
A5/E
x400
An inversion is the same chord with a different note lowest. The name changes to a slash name because the bass is what a listener hears as the foundation.
