DFRobot DFR0282 Beetle - The Smallest Arduino

Beetle is one of the smallest Arduino Leonardo boards available on the market. It offers minimal size without compromising functionality. It has an Atmel AtMega32u4 running at a clock speed of 16MHz and has plenty of interfaces: 10 digital pins, 5 analog pins and 4 PWM pins. To further make it user-friendly, it is compatible with Micro USB so that direct programming and testing is no longer a headache. The ATmega32U4 comes pre-burned with a bootloader that allows you to upload any new code that is applicable to Arduino Leonardo.

As the smallest Arduino Leonardo, it enjoys similar powerful functions. Beetle aims to solve the problems of a low-cost controller, like ease-of-use and provides a low-cost solution for disposable projects. It is ideal for applications like DIY projects, workshops, gift projects, E-textiles and educational applications for students who can not afford spending too much on hardware.
