#42654 Smart Meter PCB

Posted by firestar on 03 January 2013 - 06:36 PM

Hi All,

I made my first design for a PCB using Fritzing. It will be used to read out the P1 port of my meter. I have this currently built up on my breadboard and seems to work nicely.

It has an EEProm for storage of settings (NTP Server, IP settings, Serial settingsetc..)

FET for signal inversion

Two LEDs for Web activity and P1 Activity

A switch to broadcast UDP messages to my AddressServer (based on BOOTP) to externally set IP parameters.

As I'm not an electronic designer, I'd like to get some feedback on the design. I tried to segregate the +5VDC as much to the bottom plane and the grounds to the top plane.

I'll make a shield out of it, but I have reduced the print to what I need in space (and drop price), that's why top left pins will not be used.

Thanks in advance.
