Intel NUC NUC5i5MYBE

Pinmuxing on the 5th generation Intel NUCs is done in the BIOS. This is only tested on bios 0024+ (MYBDWi5v.86A). By default the custom solution header is disabled, currently in Linux (as of 4.2). Both i2c buses are currently supported.

The NUCs supported are the NUC5i5MYBE & NUC5i3MYBE which also come as the NUC5i5MYHE and NUC5i3MYHE motherboards. It's possible that others expose the IO in a very similar way so could be supported, get in touch if you have one!

In the BIOS you are required to enable the following: Devices -> Onboard Devices - GPIO Lockdown Select I2c under GPIO for the 12/13 14/15 pins

Interface notes

I2C Depending on your system you may need to load i2c-dev

Custom Solutions Header mapping

The mapping is the same as the DE3815tykhe.
