Product Code: DFR0282



The new generation "Beetle" controller derives its core notion from minimalism without compromising functionality. It uses the Atmel AtMega32u4 (datasheet) @16MHz clock and has expanded amounts of interfaces: 10 digital pins, 5 analog pins and 4 pwn pins. To make it even easier to use, there is an on-board micro USB so programming and debugging is no longer a headache. You use it like a regular Arduino Leonardo (Select "Arduino Leonardo (tools >board > Arduino Leonardo in Arduino IDE)), the ATmega32U4 comes preburned with a bootloader.

As a minimalized version of Arduino Leonardo, you don't have to give up on the performance, it's the same microcontroller as the full-size board. This small and inexpensive Arduino is great for low-cost projects, gift projects, wearables, etc.
