Technical Specifications
Technical Summary
The Quanta BLGNB7 project, board number B2A147, is an Arrandale platform motherboard using an rPGA 989 socket paired with the Ibex Peak-M PCH. Graphics are handled by an Nvidia GE/LP discrete GPU, with support for UMA configurations. The system uses dual-channel DDR III memory across two SO-DIMM slots. Power management is handled by an ISL88731C charger IC and multiple voltage regulators including the PM6686TR, RT8207LGQW, G5602R41U, RT8015AGQW, ISL62882CP, ISL95870AHRZ, and RT8152E. The embedded controller is an NPCE791L32, and the audio codec is a CX20587. Networking is provided by an Atheros LAN controller. The clock generator is an SLG8LV595VTR. The board includes a 3-in-1 card reader and an HDMI level shifter.
