Arduino boards with ATmega32U4 (Leonardo, Micro) require manual bootloader entry by double-pressing reset.

File Format

Arduino AVR boards use Intel HEX format (.hex files). When compiling in Arduino IDE, use "Export Compiled Binary" to generate the .hex file.

Bootloader Entry

  • • Uno/Nano/Mega: Automatic (press reset or connect)
  • • Leonardo/Micro: Double-tap reset button quickly
  • • Pro Micro: Short RST to GND twice
