Mechanical interface | Cypress Semiconductor
A client has asked me to redesign a hardware design to be Arduino Compatible (specifically for the PSoC 4, but also in general).
Is there anything resembling a standard document for interfacing to Arduino boards? So far all I've found is "here's an existing board, copy that" with no bill of materials (mainly the stacking connectors) or other mechanical info like min/max board height, component clearances, etc.
Also, electrical information like voltage levels (are these 3.3V, 5V, or ???), standard functions for the data pins (default Chip Select pins, SPI pins, etc?) and what power I can draw off the 3.3V and 5V outputs from the mother board (and are both voltages always there?)?
