Technical Specifications
Technical Summary
This Wistron Ares-1 (LAR-1) Cometlake-U motherboard, project code 4PD0HK010001, uses board number 18834-1 and document number A4199, dated 2020-03-19. The platform is Intel Cometlake-U with DDR4 memory down architecture. The embedded controller is an NPCE288. The system uses a 16MB SPI flash for BIOS. Audio is handled by a Synaptics CX11880-11Z codec. Power management includes a BQ25710ARSNR battery charger/selector and multiple DC/DC converters from Texas Instruments and ON Semiconductor. The integrated LAN is an Intel 219LM/V, and wireless connectivity is provided by an Intel Jefferson Peak module. A Realtek RTS5232S-GR card reader and a Parade PS8747B USB hub are present. HDMI connectivity uses a Parade PS8407A re-driver. Thermal monitoring is managed by NCT7717U and NCT7718W sensors.
