The cpu for that is a broadcom BCM2835.  The best guesses for that part is somewhere in the $3 range.  Unlike the CHIP, it has no onboard flash, or wifi.  It does have HDMI.<p>Personally, I don&#x27;t see how the Zero could cost less than $5 to make.  Even if the BCM2835 is $2, there&#x27;s the 512MB ram, various connectors, PCB, etc.
