MinnowBoard MAX is an open hardware embedded board designed with the Intel(R) Atom(TM) E38xx series SOC (Fromerly Bay Trail).
For product overview and faq see http://www.minnowboard.org/faq-minnowboard-max/
For technical details see http://www.elinux.org/Minnowboard:MinnowMax
mraa has only been tested with 64 bit firmware version 0.73 or later.
The low speed I/O connector supported as per table below. This assumes default BIOS settings, as they are not dynamcially detected If any changes are mode (Device Manager -> System Setup -> South Cluster -> LPSS & CSS) them mraa calls will not behave as expected.
Documentation shows i2c on bus #5, ACPI shows it on bus #6, but driver uses bus #7.
SPI operation is not currently supported
