Keyes new beginner starter kit pay more attention to beginners learning. Users can get rid of the difficult technological learning from module used to quick start production.The suite is a collection of some commonly used electronic components combining we provide graphic tutorials let lovers progressive study the application of the Arduino. After contact with the Arduino you will find that with the Arduino and electronic components products feel artistic aesthetic. We use development board is Funduino UNO R3 version of the controller is the official improved version fully compatible with the official UNO R3. Design aspects connect power conversion there we convert the DC - DC transformation improve the use efficiency and will not hot board to work long hours. Improved the digital interface and analog interface to turn him into a + 5 v &gnd interface it is very convenient by sensor and the expansion of other modules. When we want to use a 3.3 V voltage when making development environment believe a lot of people very headache official version only a set of 3.3 V interface is not enough to use so we set the conversion between 3.3-5 V just dial switch is OK.
