Which ports and pins are available?

Hi,

I looked through all of the marketing and technical pages I could find for information on exactly what ports and pins are available on the external body of this device but there doesn’t see to be much info. There isn’t even a photo of the top or sides of the device anywhere I could see!

Is there an audio jack exposed to the outside? Does it support input or only output? There are two pins on one side that I can see - what do these connect to? Which of the GPIO pins are exposed to the outside, and where?

Thanks very much for any info!

Chris.
