Technical Specifications
Technical Summary
The Quanta ZRW project (Document Number 3A148, dated July 20, 2015) is a motherboard based on the SKY LAKE ULT 15W CPU platform. The system block diagram indicates support for discrete GPU options including N16S-GT/GC6 and N16V-GM/WO GC6. The embedded controller is an IT8987, and the audio codec is an ALC255. The BIOS/SPI flash configuration is 8M+4M. Power management is handled by a BQ24780RUYR battery charger and multiple voltage regulators including NB681GD-Z, ISL95859HRTZ-T, RT8068AZQW, RT8237CZQW, TPS51225, and UP1658RQKF. Memory architecture is Dual Channel DDR III using DDR3L-SODIMM modules. Networking is provided by a Realtek RTL8111H LAN IC, and the card reader controller is an RTS5170.

Technical Summary
This Quanta Computer Inc. USB board, documented under project "USB board" with document number ZS8, reached revision 3B as of Tuesday, May 05, 2015. The schematic includes revision history entries from January 2014 through August 2014, documenting modifications such as USB trace EMI filter addition, resistor value changes from 91 ohm to 90.9 ohm, connector pin definition updates, and SD card circuit adjustments including LDO addition for high-speed read speed issues. The board features USB connectors CN1 and CN2, with associated passive components including capacitors C1 (0.1u/10V), C3 (100u/6.3V), C14 (70p/50V), and C10 (2p). Mounting holes HOLE1 through HOLE5 are defined with specific pad types including H-TC102BSD102PT1, O-ZRT-11, SPAD-ZRT-1NP1, and H-C98D98N1.
