   1 Intel NUC NUC5i5MYBE                             {#nuc5}
   2 ====================
   3
   4 Pinmuxing on the 5th generation Intel NUCs is done in the BIOS. This is only
   5 tested on bios 0024+ (MYBDWi5v.86A). By default the custom solution header is
   6 disabled, currently in Linux (as of 4.2). Both i2c buses are currently
   7 supported.
   8
   9 The NUCs supported are the NUC5i5MYBE & NUC5i3MYBE which also come as the
  10 NUC5i5MYHE and NUC5i3MYHE motherboards. It's possible that others expose the IO
  11 in a very similar way so could be supported, get in touch if you have one!
  12
  13 In the BIOS you are required to enable the following:
  14 Devices -> Onboard Devices - GPIO Lockdown
  15 Select I2c under GPIO for the 12/13 14/15 pins

  18 ---------------
  19
  20 **I2C** Depending on your system you may need to load `i2c-dev`

  22 Custom Solutions Header mapping
  23 -------------------------------
  24
  25 The mapping is the same as the DE3815tykhe.
