Technical Specifications
Technical Summary
The Wistron LCO-1 motherboard, documented under project code Dasher-1 with board number 91.4KJ01.01MH0227-1M, is built around the Intel Sandy Bridge CPU platform paired with the Intel Cougar Point PCH. Graphics are handled by the integrated Intel graphics core. System memory consists of two unbuffered DDR3 SODIMM slots operating at 1333MHz. The embedded controller is a VT1317, and the audio codec is an ALC269. Power management is handled by a BQ24742 battery charger/selector, with multiple DC/DC converters including TPS51220ARSN, VT357FCX, VT356FCX, MAX1510, and VT355FCX. The BIOS is stored on a SPI-FLASH device. Networking is provided by a RTL8111E LAN IC and an Intel LEWISVILLE WLAN card. The board also features a USB2514B USB hub, an EMC1428 thermal sensor, an R4F2113 card reader controller, and a PI3L500AZFEX HDMI level shifter.
