Report a Faulty Part

Something in your kit stopped working, or never worked at all. We will send you a new part — you keep the old one, there is nothing to post back to us.

Before you fill this in, one thing worth trying: unplug the part that is dead and move it to a different port on the expansion board. If it lights up there, the port is at fault; if it stays dark everywhere, the part is. That single test tells us what to put in the envelope, so tell us what it showed.
