Hi,
I have a Kulp K16A-B and am considering adding pushbutton input to trigger a sequence start. In the information for the controller it mentions "One header provides access to the I2C bus and 8 GPIO pins for additional push buttons or other triggers a user may need." I'm trying to determine what header that is. I see on the controller a 20 pin connector labeled I/O-EXP. I also see in FPP gpio inputs connections to pca9675 and is 20 pins. Some of these pins have voltages labeled on the board so I don't want to assume that those pins not labeled are gpio pins. Does anyone here know if this header will work for attaching push button sequence start on the Kulp controller or where I can find an official pinout of this connector on the controller? Thanks.
