Technical Summary
This ASUSTeK GX502GX motherboard, revision R1.2 dated February 21, 2020, is built on the Coffeelake H platform with a CNL PCH-H HM370 southbridge. The system supports DDR4 memory via one SO-DIMM slot and one on-board memory configuration. Graphics processing is handled by an NVIDIA N18E-G3/G2/G1/G0 GPU paired with GDDR6 VRAM. The embedded controller is an IT8225, with an additional EC IT1525VG-128/CX for keyboard and touchpad management. Audio is provided by a Realtek ALC3288-CG codec. Networking includes an RTL8125-CG Gigabit LAN controller and an AX201.D2WG.NV WiFi/BT module. The board features a dedicated SPI ROM for BIOS storage, a slave charger architecture, and a TS3DV642A0RUAR HDMI level shifter. Additional connectivity is supported by a GL9901AS14151 USB redriver and an RTS5170 card reader controller.
