Technical Specifications
Technical Summary
The NH55RZQ motherboard is built around an Intel processor and PCH architecture, supporting DDR4 SO-DIMM memory across two channels (CHA and CHB). The system is controlled by an ITE IT5570 EC/KBC, with the IT55701 package variant noted. Graphics are handled by a discrete VGA solution with dedicated frame buffer interfaces, NVVDD, FBVDDQ, and PEX_VDD power stages. The board integrates an RTL8411B combo card reader and LAN controller, alongside an M.2 WLAN+BT module. Power management includes a dedicated AC_In charger section and multiple regulated rails including VDD3, VDD5, 5V, 5VS, 3.3V, 3.3VS, VDD1.05V, VCCIO, DDR 1.2V/0.6VS, 2.5V, VCC_Core, VCCGT, VCCSA, and 1.05DX_VCCSTG/VCCSFR_OC. The schematic diagrams are based on version 6-7P-NH5E6-002.
