DFROBOT Beetle-The Smallest Microcontroller Pin Definition

The Beetle is DFRobot’s smallest microcontroller compatible with Arduino Leonardo. It features V-shaped, large-sized, gold-plated IO ports for easy wire attachment and can even be sewn directly onto clothing using conductive thread.

Equipped with an Atmel ATmega32U4 clocked at 16MHz, it offers a variety of interfaces including 10 digital pins, 5 analog pins, and 4 PWM pins. Programming and testing are made easy with its Micro USB compatibility. Simply select “Arduino Leonardo” in the Arduino IDE to upload new code. The ATmega32U4 comes preloaded with a bootloader.

DFROBOT Beetle - The Smallest Microcontroller-compact size: 20mm X 22mm

Application

Miniature industrial embedded devices (micro robots)
Wearable devices (smart glasses, AR headsets)
Smallest main controller compatible with Arduino Leonardo
Microcontroller used in environmental monitoring stations

Size: 20mm*22mm*3.8mm

The Beetle is designed to provide a low-cost solution for disposable projects such as DIY projects, workshops, gift projects, E-Textiles, and educational purposes.

It offers an affordable and easy-to-use option for students and makers who may not have the budget for more expensive hardware.

As the smallest 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. 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. 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. Beetle is a extremely the smallest Arduino leonardo board. It derives its core notion from minimalism without compromising functionality.
