Arduino A000057 Leonardo with Headers

welcome to the pain tech bite size reviews this one for the arduino leonardo this is a 16 megahertz chip on in it's a slightly different chip to the uno it's actually a very similar form back to the uno but it's actually a little bit different in quite a few ways um in particular has a very different chip on board at mega 32 u4 on board instead of the atmega328 it runs at 16 megahertz which is the same as the uno um at 5 volts same power requirements 7 to 12 volts it's got built-in little udc socket here or you can run it by the usb usb type is a micro type b so it's a very very small usb port it will automatically change over between those power sources recommended is 7 to 12 volts as your incoming supply power it will just about get by on between 6 and 20 volts dc you're going to make some sacrifices in stability or capability in some respects so i recommend sticking between 7 to 12 v
