The new generation "Beetle" microcontroller from DFRobot based on the Atmel AtMega32u4
To further make it user-friendly, it is compatible with Micro USB so that direct programming and testing is no longer a headache. Select "Arduino Leonardo (tools >board > Arduino Leonardo in Arduino IDE), the ATmega32U4 comes preburned with a bootloader that allows you to upload any new code that is applicable to Arduino Leonardo.
As a minimized version of the Arduino Leonardo, it enjoys similar powerful functionalities. The Beetle aims to solve problems of low-cost controller, ease-of-using properly, and to provide a low cost solution for DIY projects, workshops, gift projects, E-Textiles and education.
