max Current of Duet 3 Expansion 3HC on 5V rail

M4us

How much current can i draw on the 5v out of the 3HC expansion board?
if I need around 2 A should i just step down one of the 12V outputs?

M4us

but this is for the 6HC not the 3HC Expansion right?

Veti

but unfortunately there is no mention what the 5v can handle.

@dc42 can you comment?

M4us

@Veti yeah i saw the docs about the 3hc and it mentions how much i can draw from the 12v outputs but not how much from the 5v

dc42

Up to 0.8A from 3.3V and 5V combined, of which no more than 0.5A from 3.3V.

I've added a note.
