Technical Specifications
Technical Summary
The Wistron BOLT WHL1 motherboard, project code QRQY00000009, board number 17938 revision 1, is a Whiskey Lake platform design dated 2018/12/12. The system uses an Intel CPU with DDR4 SODIMM memory across two slots, supporting both UMA-only and discrete Optimus graphics configurations. The embedded controller is a MICROCHIP MEC1416 with an 8MB flash ROM. The BIOS is stored on a 16MB SPI flash ROM. Charging is managed by an ISL95522/ISL9538 charger IC. Audio is handled by a REALTEK ALC3204 codec. Networking includes a REALTEK RTL8111H or RTL8107E LAN IC and a 2.11a/b/g/n BT V4.0 combo CNVi M.2 WLAN module. The card reader uses a Realtek RTS51446, and the HDMI level shifter is a REALTEK RTD2166. The system also includes a NUVOTON NPCT750 TPM 2.0 module and a TUSB54671 USB hub IC.
