DFRobot Beetle (ATmega32U4)
Overview
The DFR0282 Beetle is an ultra-small, low-profile microcontroller board based on the ATmega32U4. Measuring only 20mm by 22mm, it is designed for space-constrained projects and features large gold-plated IO pads that facilitate easy soldering or conductive thread attachment.
Why Choose This Part
This board features a built-in Micro USB port for direct programming and power, eliminating the need for external FTDI adapters. It includes 10 digital pins, 5 analog channels, and 4 PWM outputs while maintaining 5V logic compatibility for easy interfacing with standard sensors.
Applications
Key Specifications
Getting Started
The Beetle comes pre-burned with the Arduino Leonardo bootloader and is compatible with the Arduino IDE via a standard Micro USB cable. Select Arduino Leonardo from the board manager to begin programming using the native USB interface.
Also Consider
Arduino
- A larger but more comprehensive ATmega32U4 board with more IO pins and a standard DIP footprint for breadboarding.
Arduino
- Offers more memory and pins in a similar form factor, though it lacks native USB HID support.
