Enterprise Power module - EPower
« on: 2018.January.30. 10:54:55 »
A few days ago, Zozo asked me about the possibility of building a replacement for the 7805 stabilizers in EP.
There are many cheap replacements available, but most of them are of very poor quality.
They are in themselves a risk of damaging the EP.
I looked closely at the motherboard and the existing power circuits.
If we remove all the elements that we want to replace with the new solution, there is a lot of space left on the mainboard.
Initially I drew a PCB with a complete + 5V and + 12V power supply matching the emptied space.
I still have to make a template and try on the real mainboard (mainly to check the height).

We'll see what comes out.
PCB samples on the way.

Almost good. Almost ...
I have mistaken in the order for the main stabilizer. I've ordered type for bad voltage :(
So we'll have to wait for the tests for a while.
At now only the 12V supply part is working properly.
It looks like it will fit :)
