Ethernet Shield

Ethershield with USBBB Ethershield Backside

I implemented a Ethernet Shield for Breadboards, like usbbb, which runs with ENC28J60

Here you can find the PCB Schematics and Board:

Attention: these Board and Schematics files may not work, because I messed up with the RJ45 MagJack. (See below) One Problem is that i want to use isolation milling all the time, so also this board was milled. but this is sometimes quite problematic, e.g. the RJ45 is really difficult to connect, if i would use other techniques to create my PCB, i would'nt have that much problems with the PCB.

MagJack

Every MagJack is different! The pinout is specific to every Connector, so please read the datasheet and make shure you use the right one!

Partlist

Exported with Eagle - Most of the parts are SMD, all the resistors which are not SMD, are also soldered as SMD, because normal does not look good :)

My ethershield is currently working without the ferrit but it is considered to do so. Also a very good way to get 25MHz Quarzes is to solder one out of an old network card. Even mainboards with internal ethernet got one on them (i got mine from such a thing).
