IO Expander Module


The IO Extender w/ 8 ft. Harness firmware allows the use of a Microsquirt as an IO Extender w/ 8 ft. Harness with minimal D.I.Y. and straightforward

software configuration. When used with MS3 or  it can offer a useful I/O addition:

7 Analog inputs (0-5V variable)

2 Wheel speed inputs (VR or hall type)

2 Wheel speed (hall type) or ground-switch inputs

1 dedicated ground-switch input

2 high current PWM/switch ground-switching outputs

4 mid current PWM/switch ground-switching outputs

1 low current PWM/switch 0-12V outputs

By design, the inputs and outputs have a fixed function to simplify configuration. All configuration is performed through TunerStudio in the MS3 settings pages.
