Beetle

The new generation "Beetle" controller 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 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. 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 minimalized version of Arduino Leonardo, it enjoys similar powerful functionalities. Beetle aims to solve problems of 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.
