A great number of the Pmod devices use SPI to communicate but one can only plug in 2 such modules into the Pmod shield Uno32 (and the second one will have to use DSPI1 which shares pins with UART1).

I would like to see a shield that looks identical to the Pmod Shield Uno in terms of connectors, but have all 5 JA--JE connectors on the DSPI0 bus. Maybe with some sort of pin array to connect jumpers for mapping interrupt and slave select pins.

Are the board layout files available for the Pmod Shield Uno? I could take a stab at designing such a board but I would rather not start from scratch.
