RE: P24 current measurements.

Mark,

yes right, I forgot your overvoltage settings that I had read about in your recent thread. Amazing that this results in such a substantial increase in power consumption on the 5v rail.

Well, on your 'PSU improvements part 3': Now that you have optimized your pico already, I'm afraid there's nothing much you can do to optimize 5v when leaving the pico in place, at least I don't see it. The next step IMHO really would always have to involve taking out the pico and supplying three separate voltage rails externally (linear, battery, in whatever configuration). And unless you use some module to do the timing and ramp up stuff to power up right (provided there is one which I belive is the case, I just haven't managed to track it down) this has to involve switching over from ATX to linear or similar after booting. I would not consider it too complicated, there's info and documents how to do this, but it surely involves soldering and a bit of electronic knowledge, and some courage ;-) You see there's a reason why almost nobody (at least as far as I can see, I'd love to be corrected) has taken that step to surpass pico and power P24 rails independently...

I can't think of any more useful or encouraging news, maybe others can look at it from different angles and come up with a promising way that I haven't seen?

Best,
Robert
