Technical Specifications
Technical Summary
This Quanta Computer Inc. ZHK331 project motherboard is built on the Intel Bay Trail-M platform with a UMA graphics architecture. The system firmware is stored on a 1.8V BIOS SPI ROM with a capacity of 64Mb. The embedded controller is an NPCE985 in an LQFP128 package, supported by a dedicated 3.3V EC code SPI ROM of 1Mb. Audio is handled by an ALC283 codec in a QFN package. The board supports a single DDR3L SO-DIMM module for memory expansion. Power management includes an OZ8690ALN charger IC, alongside NB670/NB669, APW8804, ISL95833, and APW8819 power ICs, with a G5934 discharge IC. Connectivity features include a LAN IC, a WLAN/BT combo module, a Card Reader SDIO interface, and a thermal sensor.
