1 Intel(R) Minnowboard Max {#minnowmax}
2 ========================
3 MinnowBoard MAX is an open hardware embedded board designed with the Intel(R)
4 Atom(TM) E38xx series SOC (Fromerly Bay Trail).

13 mraa has only been tested with 64 bit firmware version 0.73 or later.
17 For SPI support you need to load the low_speed_spidev kernel module and that
18 will create the /dev/spidev0.0 device node. Mraa only knows about this one SPI
23 The low speed I/O connector supported as per table below. This assumes default
24 BIOS settings, as they are not dynamcially detected If any changes are mode
25 (Device Manager -> System Setup -> South Cluster -> LPSS & CSS) them mraa calls
26 will not behave as expected.
28 Documentation shows i2c on bus #5, ACPI shows it on bus #6, but driver uses
