General Purpose Inputs & Outputs

The GPIO (general purpose input/ output) board has a variety of functions – the first released application is the MegaShift automatic transmission controller, but it has circuitry capable of many other functions. It’s possible to modify one to be an ignition controller, record EGTs, or many other applications if you have the right parts. Because of the GPIO’s flexibility, we offer these kits a bit differently. There is a GPIO base kit that includes the GPIO board, all SMD parts, case, and pigtail harness. The application-specific parts are sold as separate kits, allowing you to customize the GPIO board for your specific use.

  • MegaSquirt GPIO Black Anodized Case

    $48.00

    GPIO board case. This one has an AMPSEAL cutout on one end, and the other end blank. You may drill a hole if using the stereo jack for serial communication, or use the AMPSEAL for that. Note that these cases are a bit of a tight fit - we recommend solderi...
