# Transformer, PIC controller & BOM

## Question

Asked by paulmichael2014 on 2014-02-14 in IO Modules.

Hi guys,

on the WIZ550io product photo I see a transformer, but in the schematics V1_1 I cannot find it.
Maybe the photo is of an previous release. What version do I get if I order the module?

It would be awesome if you can supply the source code of the PIC12F519 controllor or at least some
documentation what and how the initial configuration works.

Also I would love to see a Bill of Materials of this module.
I cannot identify the PN of the Ethernet Jack with embedded magnetics.

Thanks for your support.
