The Raspberry Pi B has landed on the Maker World like a 40-GPIO pinned, quad-USB ported, credit card sized bomb of DIY joy. And while you can use most of our great Model B accessories by hooking up our downgrade cable, its probably a good time to upgrade your set up and accessorize using all of the Model B ‘s 40 pins.That’s why we now carry the Sintron GPIO Board Plus with Color 40 Pin Ribbon Cable for Raspberry Pi B .
