Technical Specifications
Technical Summary
The Huaqin NB2329 V4.0 motherboard is built on the Intel Gemini Lake Refresh Platform, supporting Pentium N5030 or Celeron N4020 processors with integrated GLK-R SOC graphics. The board utilizes an ITE8987 EC/KBC with an EC-ROM SPI interface for programming. System firmware is stored on a SYSTEM SPI FLASH ROM. Memory architecture consists of Single Channel DDR4 at 2400MHz, with multiple DRAM configuration options including Samsung, Micron, and Hynix 8Gb and 16Gb components. Power management is handled by a BQ25700A Buck Boost charger, with PMICs RT5077AGQW, RT6256B, and RT9610C generating core voltage rails. Audio is provided by the ALC3287 codec. Connectivity includes WLAN 1216 HP2 AC, CYW20730 BT controller, and multiple card reader ICs (RTS5232, RTS5830, RTS5876). Thermal monitoring is managed by the NCT7719W discrete thermal sensor.
