EMX Current sink and source


How much current can the EMX module pins sink/source.

I would like to source current for the Ethernet link and speed LED’s (J13 and J14) rather than sink it like in the EMX DevSys.

Any help greatly appreciated

It depends on what is also connected to other pins.
If I remember well you should not exceed a total of 20mA and 3-5mA per pin. But maybe GHI can confirm or not.

Maybe you can dig into the LPC2478 user manual. For an other chip, this was also a big question: https://www.ghielectronics.com/community/forum/topic?id=1290&page=1
