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 16 17 Interface notes 18 --------------- 19 20 **I2C** Depending on your system you may need to load `i2c-dev` 21 22 Custom Solutions Header mapping 23 ------------------------------- 24 25 The mapping is the same as the DE3815tykhe. 26 27 | MRAA Number | Physical Pin | Function | Notes | 28 |-------------|--------------|--------------|----------------------| 29 | 0 | 1 | 1.8V sby | | 30 | 1 | 2 | GND | | 31 | 2 | 3 | HDMI_CEC | | 32 | 3 | 4 | DMIC_CLK | | 33 | 4 | 5 | 3.3V sby | | 34 | 5 | 6 | DMIC_DATA | | 35 | 6 | 7 | Key (no pin) | | 36 | 7 | 8 | SMB_ALERT# | | 37 | 8 | 9 | 5V sby (2A) | | 38 | 9 | 10 | SCI_SMI_GPIO | | 39 | 10 | 11 | PWM[0] | | 40 | 11 | 12 | PWM[1] | | 41 | 12 | 13 | I2C0_CLK | /dev/i2c-0 SCL | 42 | 13 | 14 | I2C0_DATA | /dev/i2c-0 SDA | 43 | 14 | 15 | I2C1_CLK | /dev/i2c-1 SCL | 44 | 15 | 16 | I2C1_DATA | /dev/i2c-1-SDA | 45 | 16 | 17 | SMB_CLK | | 46 | 17 | 18 | SMB_DATA | | 47
