Hi.

Can i connect two teensy card to the same ground connections for all my components?

Or do all components connected to one teensy have their own ground connections?

Reference the Ground topic in the forum. ;) The Ground on the Teensy's is the same as the USB Gnd/PC power supply Gnd/ House Gnd/ Any other power supply Grounds. ;) Only the AGND on the Teensy is separate.

Example, If you a Ground Bus, (which you should) one side of a switch goes to it, the other to the input of the Teensy.

Thanks.

So ofcourse if the button is grounded via one teensy it is not nessecary to ground it again on the other teensy because in the usb they both connect to the same ground.

Thank you.
