Are the Stemtera power rails already connected to 5V and ground?

Dumb question, but just want to be sure. Are power rails already connected to 5V/3.3V and ground inside the Stemtera chassis? Or am I suppose to connect the power rails to the 5V and Gnd pins like on a normal breadboard?

The rails are not connected, they’re just like a regular breadboard so you’d need to jumper them to a power source and ground. :slight_smile:
