Technical Specifications
Technical Summary
The Wistron Bumblebee (LBB-2) Cometlake-U motherboard, project code 4PD0JH010001 and board number 19733-1, is built around the Intel Cometlake-U Series platform. It features an NPCE388 embedded controller and a Realtek ALC3287-CG audio codec. The system memory consists of two DDR4 memory-down modules. Power management is handled by a BQ25700ARSNR battery charger and multiple DC/DC converters including TPS51285B, NCP302045LMNTXG, NCP81253MNTBG, NCP81218PMNTXG, and RT5797ALGQW. The board integrates an Intel 219LM/V Gigabit Ethernet PHY and an onboard Harrison Peak WLAN module. Storage is supported via a 32MB SPI flash for BIOS and an M.2 2280-S3 SSD slot. The graphics subsystem utilizes the integrated GPU with eDP 1.4 display output.
