Hi,
I am trying to design a platform that will consist of an Arduino Duemilenova, a Ethernet shield, and another custom made PCB with a MAX232 (using its both serial channels) and some other minor components..
I need to decide which ACDC adapter to use before I order the PCB. My main problem is the Ethernet shield, I only have the chip consumption (around 183mA according to de dathasheet) but I have no idea about the other components in that board..
Any idea of what minimum current will I need?
Thanks a lot!
