Eagle PCB CAD Services

Eagle PCB CAD is a software package that allows a user to enter a pictorial schematic as a netlist. A board can be built from this netlist; parts arranged and connections made by Printed Circuit copper runs. I am skilled in entering the circuit into the Eagle CAD package; Placing the parts and sizing the board then making the connections. I can then send you the gerber files to make the board and educate you in this process. I place parts logically and then use the autorouter. I do not draw all lines but use signal names similar to what ADAFRUIT does in their eagle schematics. Please contact me for this service using the contact box below.

Consulting fee is $45 / Hour plus expenses.
EAGLE CAD fee is $25 / Hour plus expenses.
