How to Use Arduino Leonardo without Headers
Begin by soldering male header pins or directly attaching jumper wires to the board’s solder pads for your chosen connection style. Attach a micro USB cable to your computer, open Arduino IDE 1.0.1 or later, select “Arduino Leonardo” under Tools > Board and the appropriate COM port, then write and upload your sketch. For standalone operation, supply 7–12 V to the VIN pin or barrel jack; the onboard regulator delivers 5 V to the microcontroller.
