This product is also compatible with SimHub.

This display is our implementation of the popular open source project  iFlag.

The hardware is not based on an Arduino board but we designed our own pcb, in order to obtain a better form factor.

We also integrated all the iFlag functionalities into our SimDash, so that no addition software is required. The features of the original iFlag display have been expanded so that it can be used as a gear indicator too, in particular when used with simulators different than iRacing.

Main features of this product:

  • When using SimDash and iRacing: displays all the flags, safety warnings, starting lights and other warning signs. The table at the bottom of this page contains the list of all the signals available. These signal are only available with iRacing.
  • With SimDash and iRacing or any other simulator: Optionally the display can be used as a gear indicator. The color of the indicator can be customized and there are other configuration options to make the indicator blink based on RPM values or, with some simulator, based on the state of the in-game shift light.
  • When using SimHub with the iFlag display, flags from all the supported games will be shown, not just iRacing.
  • The brightness of the display can be adjusted in the iFlag configuration screen, in SimDash, or with the two push buttons on the back of the display.

Configuration screens

The configuration of the display is very simple. The first dialog allows the brightness to be adjusted. But it is probably just faster to perform the same operation using the push buttons on the back of the display.

The next section allows you to choose which messages are shown by the display. We would suggest to leave everything ON for the best experience:

Finally, in the Gear Indicator tab you can select whether you want the iFlag display to show the gear position, when not displaying other information.

There are other configuration options like the color for the gear indicator and blinking options:
