Hi,
        Which software can I use to design small form factor PCBs, so that I can create my own expansion board to interface with the Overo motherboard. 

My requirements are quite simple, I just need to have a small PCB so that I can populate it with the following connectors for my Sharp LQ043T1DG01 LCD display module:

a. Hirose FH12A-40S-0.5SH (55) Top contact type, for the TFT LCD panel
b. 0.5mmP 4Pin FPC (Reference Connector: Kyocera Elco Corporation Product No.: 6298 Bottom contact type), for the LED back light
c. 1mmP 4Pin FPC (Reference Connector: J.S.T. Mfg Co., Ltd, Product No.: 0.4(1.0)9FLH-SM1-GB-TB), for the touch panel 

Is there some software that already has all these connector parts pre-defined, so that I don't have to worry about dimensions, etc of the connectors? The pins on the FPC connectors are so tiny and closely spaced, I don't want to make a mistake in the PCB design, and I want to get it right the first time.

Best regards,

Elvis Dowson
