EM1000-00 and -01/-02

Small hardware changes were made to the EM1000 since its first release. Currently, Tibbo supplies version "-02" of the module, while "-00" was the first version produced. The main difference is in the Ethernet IC: the "-00" used Davicom's DM9000, while the "-01" and "-02" feature the newer DM9000A. This change reduced the module's current consumption and operating temperature. Unfortunately, this transition requires certain alterations to the way Ethernet magnetics and RJ45 are wired to the module. Tibbo apologizes for any inconvenience caused!

Throughout this document, differences between the hardware versions of the module are highlighted in pink. Please, note that from the programming standpoint, there are no functional differences between any of the versions.

The pictures below show the original "-00" and the "-01" versions.

This is how the original "-00" version looks like:

And this is how the "-01" version looks like:

The "-02" version added a small sticker on the board that identifies which memory capacity it carries — 512KB or 1,024KB. There were no alterations to the hardware from the "-01" version.
