SPI-D is a compact USB digital speedometer designed for racing and performance applications. In addition to speed, it can display a wide range of vehicle data at a glance.

The bright red three-digit display ensures excellent visibility in all conditions. Display brightness is fully adjustable via software, allowing you to fine-tune it for day or night use.

SPI-D connects directly to any USB port using a USB Type-C cable and requires no external power supply — simple, clean, and reliable.

Through the configuration software, you can:

• Adjust display brightness
• Choose speed units (km/h or mph)
• Display RPM, gear position, race position, lap number, fuel level, water temperature, oil temperature, or oil pressure
• Enable blinking alerts with three selectable blink rates based on data thresholds

Multiple SPI-D units can be used simultaneously, making it easy to build a fully customized dashboard.
