The fuse provides an extra protection layer to the computer's internal protection mechanism, safeguarding the system from currents above 500mA. Its function is to protect the built-in USB ports from shorts and overcurrent. This microcontroller features a resettable polyfuse. The external power source can either be a battery or an AC-DC adapter, and the board will select the power source automatically. You can power the Leonardo using the micro USB connection or an external (non-USB) power supply. It is vital to note the following points. ![]() Arduino Leonardo Specifications The Arduino Leonardo SchematicĪrduino Leonardo is open-source hardware, so you can build the board using this schematic and pinout file. There's also a built-in LED connected to pin 13. The Arduino Leonardo's pinout broadly falls into the following nine categories. It features 20 digital I/O pins (12 double up as analog inputs and seven as PWM outputs), a micro USB port, a 16 MHz crystal oscillator, a reset button, and an ICSP header. Comparison with Arduino UNO, NANO, MEGAĪrduino Leonardo is a board microcontroller based on the low-power, high-performance ATmega32u4 chip.Connection and Firmware of the Arduino Leonardo.Auto Reset (Software) and Bootloader Initiation.
