I am in need of a circuit schematic that I can in turn use to layour a circuit board. I also need recommendation for ICs as well. I need a design for a 64 input 64 output (128 total I/O) USB board that can easily be attached to a Visual Basic 6.0 application.
The board should be able to be individually addressed if there are multiple boards present on one computer.
The outputs need to handle 0-60V at around 12A of current.
The inputs should accept around 0-30 volts.
I don't mind what combinations of boards/chips are used, but I am trying to keep costs as low as possible. Some suggested chips would be from Cypress Semiconductor and Microchip, but anything can be used.
