TFT Gauges: Advanced Instrumentation for Modern Vehicles
Progauges products introduce an advanced digital instrument cluster and TFT smart gauge series featuring 19 configurations, ranging from 1.44-inch single-function displays to 7-inch heavy-duty dashboards. Engineered for OEM/ODM integration, this series serves commercial trucks, buses, agricultural machinery, and electric vehicles. Supporting both analog signals and the SAE J1939 CAN bus gauge protocol, it communicates directly with the engine ECU to monitor oil pressure, coolant temperature, voltage, fuel levels, and battery SOC with exceptional precision and reliability.

Product Description
Overview
TG-0301 is a 3.4-inch TFT 2-in-1 integrated smart gauge with an 800 × 800 high-resolution display, consolidating speedometer (0–140 MPH), tachometer (0–8000 RPM), and total odometer (0–99999.9) into a single interface. Two signal versions are offered: TG-0301-001 uses the SAE J1939 CAN Bus protocol to read directly from the vehicle ECU, while TG-0301 accepts frequency-based input from sources such as ignition coils and supports 4-, 6-, and 8-cylinder engines. Typical applications include heavy-duty trucks, buses, commercial vehicles, and other vehicles where a simplified dashboard layout is needed — for instrument cluster upgrades and integration. Available for OEM / ODM design development and aftermarket use, and supports integration on ICE (gasoline & diesel), Hybrid, and EV Vehicle platforms.
