DFRobot Beetle Board - Compatible with Arduino Leonardo - ATmega32U4

IntroductionBeetle is fully compatible with the Arduino Leonardo board. It derives its core notionfrom minimalism without compromising functionality.It comes with Atmel ATmega32U4 (datasheet)@16MHz clock time and has expanded amounts of interfaces: 10 digital pins, 5 analog pins, and 4 pwn pins. To further make it user-friendly, it is compatible with MicroUSB so that direct programming and testing is no longer a headache. Select "Arduino Leonardo (tools - board - Arduino Leonardo in Arduino IDE), the ATmega32U4 comes pre burned with a bootloader that allows you to upload any new code that is applicable to Arduino Leonardo.As the DFRobot smallest board compatible with Arduino Leonardo, it enjoys similar powerful functionalities. Beetle aims to solve problems of the low-cost controller, ease-of-using properly, and to provide a low-cost solution for disposable projects, such as DIY projects, workshops, gift projects, E-Textiles, and educational.
