Leonardo R3 development board atmega32u4, official version

Since the optimization project's subsequent chip is changed to MU packaging, it is fearful

Compared with other versions of RDUino, the independent USB-Serial conversion chip is used, and Leonardo innovatively uses a single chip solution.Only a piece of ATMEGA32U4 is used to achieve USB communication and control.This innovative design reduces the cost of Leonardo.The original ecological support of ATMEGA32U4 can also simulate Leonardo into mouse and keyboards, which greatly improves the application.Use RDUINO Leonardo to need a new version of Arduino IDE1.01 or above.
There are some obvious differences between RDUINO Leonardo and ordinary RDUINO. For specific content, please refer to the RDUino Leonardo guidance document:
