The sim2gauge is a small, plug and play board that lets you drive a real analogue tachometer from a PC racing game.
All supported games are listed on SimHub.
The Sim2Gauge receives data from SimHub over USB-CDC and outputs a clean, 50% duty cycle square wave scaled to your tachometer’s expected frequency range. Two on-board switches select the cylinder count, which sets the maximum output frequency:
| Cylinders | Max frequency |
|---|---|
| 2 | 200 Hz |
| 4 | 400 Hz |
| 6 | 600 Hz |
| 8 | 800 Hz |
Set the switches to match the cylinder count that your tachometer expects. Many aftermarket tachometers have their own switches inside for this, consult the product manual.
Maximum RPM is always 12000. An onboard boost converter and soft-start illumination output let you drive period-correct dashboard lighting safely from a single USB connection.
