TFT Instrument Cluster with Bluetooth Audio and Telematics

概览

描述

Modern two- and three-wheelers, as well as passenger and commercial vehicles, increasingly demand connected, visually rich, and intuitive driver information systems without adding excessive cost or system complexity. OEMs are seeking compact clusters that combine graphics, telematics, connectivity, and camera support while remaining easy to develop and highly scalable across vehicle tiers.

This system addresses these needs with a cost‑optimized, fully integrated TFT instrument cluster built on a high‑performance MCU, enabling both cluster graphics and telematics functions on a single device. With built‑in AI acceleration and extensive connectivity options, this design delivers a powerful, production‑ready platform that reduces development effort, lowers BOM cost, and accelerates time to market for connected vehicle dashboards.

System Benefits:

  • Cost‑effective, compact, and simplified real‑world vehicle instrument cluster enabling graphics and connectivity
  • AI‑ready MCU with an on‑chip neural processing unit (NPU) for edge analytics
  • Dual‑core MCU enables integration of telematics functionality alongside cluster applications, reducing overall system cost
  • Ready connectivity options, including CAN, Wi‑Fi®, Bluetooth® Low Energy (LE), GPS, and GSM 4G
  • Supports modern HMI frameworks such as Qt, Crank, SEGGER, and LVGL, enabling OEMs to deliver premium, smartphone‑grade user interfaces even in cost‑sensitive vehicle segments
