Technical Summary

The Cairns MB motherboard, designed by Core Design and dated July 20, 2018, is built around the Intel KabyLake-H processor in a BGA 1440 package, paired with the Intel QM175 PCH. Graphics are handled by a discrete NVIDIA N17E-G2 Max-P GPU. The system firmware is stored on a 128Mb SPI FLASH ROM. Embedded controller functions are managed by an MK22FN512 microcontroller, which is programmable via UART. Audio is provided by an ALC3269 codec. Networking includes an Intel I219LM LAN controller and a Marvell 88W8897 WiFi/BT module. Memory configuration consists of dual-channel DDR4 SO-DIMMs supporting up to DDR4 2400. The charging subsystem utilizes an NX5P3290UK IC with VBUS CC logic, and a PTN5110 power IC is present. Additional I/O includes an RTS5242 card reader and a TUSB546ASS MUX for USB-C connectivity.
