Arduino Micro ATMEGA32UC Board

product description: ?????????????? Development of Atmega32U4 based on Arduinos Micro MPU. Arduinos Micro has 20 channel input and output pins (7 PWM outputs and 12 analog inputs). Due to the small size, Arduinos Micro can easily be integrated into a small breadboard. Benefit from Atemga32U4, Arduinos Micro and Arduinos Leonardo like, USB communication and control can be achieved. This innovative design reduces costs. Atmega32u4 original eco-support USB function also allows Arduinos Micro analog mouse and keyboard, which has greatly improved the application.
