Intel NUC NUC5i5MYBE {#nuc5} ==================== 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. | MRAA Number | Physical Pin | Function | Notes | |-------------|--------------|--------------|----------------------| | 0 | 1 | 1.8V sby | | | 1 | 2 | GND | | | 2 | 3 | HDMI_CEC | | | 3 | 4 | DMIC_CLK | | | 4 | 5 | 3.3V sby | | | 5 | 6 | DMIC_DATA | | | 6 | 7 | Key (no pin) | | | 7 | 8 | SMB_ALERT# | | | 8 | 9 | 5V sby (2A) | | | 9 | 10 | SCI_SMI_GPIO | | | 10 | 11 | PWM[0] | | | 11 | 12 | PWM[1] | | | 12 | 13 | I2C0_CLK | /dev/i2c-0 SCL | | 13 | 14 | I2C0_DATA | /dev/i2c-0 SDA | | 14 | 15 | I2C1_CLK | /dev/i2c-1 SCL | | 15 | 16 | I2C1_DATA | /dev/i2c-1-SDA | | 16 | 17 | SMB_CLK | | | 17 | 18 | SMB_DATA | |
