DFRobot Beetle

Development Boards

Beetle is fully compatible with the Arduino Leonardo board. It derives its core notion from 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 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 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. For students and makers who can not afford too much on hardware purchasing, Beetle can be a great solution for them.
