Technical Specifications
Technical Summary
This Quanta ZHR471 (Revision 1A) motherboard is built around the Intel Braswell platform, supporting BSWN3150 1.6G QJ4T or BSWN3050 1.6G QJ4V CPUs in an FCBGA 1170 package. The system uses DDR3L memory in a 2-channel memory-down configuration. The EC/KBC is a MEC1322-LZYP in a DQFN132 package, and the BIOS SPI flash is a W25Q64FWSSIG with 64Mb capacity. Audio is handled by a MAX98090 codec in a TQFN-40 package. Power management includes a BQ24770 NVDC battery charger, RT7291A/RT7290A regulators, RT8171B, and RT5041A. The board features a SLB9655TT1.2 TPM and card reader, a TMP432 thermal sensor, and a KXCJ9-1008 G-sensor. WLAN/BT connectivity is provided via a combo module.
