Pics dug up from my ARChive...
Not sure what it is, but there should have been a good
reason I saved these on my pc...

Will the one who made this please come forward
and explain to us what nice creation this is.

Cheers !

Not sure if these are related, but they look quite similar in a way...

Cool, eh ? :lolsign:

I believe it's a POP converter from djpark. The FLuPIC uses a similar concept.

I knew you would chime in sooner or later...
Any idea what is does ? What is all the wiring on the stock Arc LS board ?

A microcontroller enables a LDO regulator via PWM. The point-to-point wiring replaces what would normally be the circuit board traces.
