A much beloved, uber hackable single board computer with wireless and Bluetooth - now with a quad-core, 64 bit CPU upgrade!Raspberry Pi Zero 2 W is a tiny low-cost computer with a massive user base that is perfect for embedded projects. It has the same footprint and 40 pin GPIO arrangement as the Zero and Zero W, so it should be compatible with most existing add-ons.Whats new though, is the very shiny quad-core, 64-bit ARM Cortex CPU - which gives the Zero 2 W (almost) comparable processing power to a Pi 3 (it runs at 1GHz, rather than 1.2GHz). The power of a full size Pi crammed into the Zero footprint - great for tiny retro consoles and any small projects that require more processing oomph than the Zero W can traditionally provide!Zero 2 W comes without a pin header - but you can find solder and solderless header options under the Extras tab, as well as suitable mini HDMI cables, micro USB power supplies, SD cards and cases.Key featuresBuilding on the success of the current Zero fami
