Use case: Some of the screens don't have touch capability, and even if they have, it is usually consuming USB port making OTG unavailable (big issue for Android development case).

Having touchpad mezzanine connected to LowSpeed IO connector (SPI-based) will resolve this issue.
Please don't forget to expand UART1 pins to be accessible through some connector or combine it with FTDI chip.
