VRM experience and rule R43

[Mark McLeod]

I mistakenly thought that I remembered having been able to put a 500ma continuous load on the 12v/500ma and a 1.2ma continuous load on the 12v/2a outputs and after a few seconds browning out the whole 12v side (on the older v1.2).

Sorry for the misinformation.

Sorry for the misinformation.

On the older revs of hardware (<1.4) that was only true on the 2 amp rail and the limit was actually 1.5 amps. So if you are unsure which rev you have keep the total budget below 1.5 and you are good to go.

The latest rev (1.4) can be identified by removing the bottom cover and identifying the solder mask color. A black solder mask is the latest Revision.
