The Beetle is one of the smallest Arduino Leonardo-compatible boards available, built around the ATmega32U4 microcontroller running at 16MHz. Despite its tiny size, it delivers the full functionality of an Arduino Leonardo with 10 digital pins, 5 analogue pins, and 4 PWM outputs.

With a built-in Micro USB connector, you can program and power the Beetle directly — no external programmer needed. Simply select "Arduino Leonardo" in the Arduino IDE and upload your code. The ATmega32U4 comes pre-loaded with the Arduino Leonardo bootloader.
