Technical Specifications
Technical Summary
This Wistron Cheetah-1T motherboard, documented under number C1144 dated May 19, 2021, is built around the Intel TGL-H CPU platform with DDR4 memory architecture across CH-A and CH-B. The discrete GPU is an N20E with dedicated VRAM across channels A, B, C, and D, supported by an NCP4549 power monitor. The embedded controller is an NPCX997KA0BX, while audio is handled by an ALC3286 codec paired with an ALC1309L smart amplifier. Connectivity includes Thunderbolt retimers A and B, a USB PD controller, an HDMI2.1 retimer, an eDP MUX, and an M.2 1216 module for LAN and WLAN. The board also integrates a discrete TPM 2.0, an APS G-Sensor, a card reader, and a Think Engine 2 module, with debug access via MIPI60 and SMBUS/eSPI interfaces.
