Technical Summary
This document is a Wistron Corporation Leia-1 SENSOR BDA board, revision A3, dated Friday, November 24, 2017, with PCB number 17a54. The sensor board integrates a HGDEDM013A-GP Hall sensor for lid angle detection via I2C communication, and a BMA253-GP accelerometer. The default I2C address for the Hall sensor is 0x18 when the SDO pin is pulled to GND, with an alternative address of 0x19 selectable by pulling SDO to VDDIO. The board includes a 5-pin ACES-CON14-9-GP connector and a 24-pin ACES-CON24-15-GP connector for interfacing with the mainboard. Power rails include 3D3V_AUX_KBC, 3D3V_S0, and 5V_S0. The schematic notes indicate a change from 3D3V_AUX_S5 to 3D3V_AUX_KBC for SNR1.29 on the MB side.

Technical Summary
The Wistron Leia-1M motherboard, project code 4PD0DA010001 and board number 17833 revision -1, is built around the Intel Gemini Lake platform. The system is powered by a BQ25700ARSNR charging IC with BD2671 architecture and TPS51225BRUKR, BD2671, and G2898K power ICs. Memory configuration supports two DDR4-ODIMM channels. The embedded controller is a Nuvoton NPCE288, and the audio codec is a Realtek ALC3287-CG. The BIOS is stored on an 8MB SPI flash. Networking is handled by a Realtek RTL8111GUSI LAN controller and a Wireless LAN Antenna Type-E M.2 2230 module. The HDMI interface uses a PS8330 level shifter, and the card reader is controlled by an RTS5146-GR IC.
