It has 23 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. You can use compatible clones interchangeably with the Leonardo for all the examples in Exploring Arduino.īuy the Arduino Leonardo from Amazon, Pololu, or SparkFun. The Arduino Leonardo is a microcontroller board based on the ATmega32U4. There are many compatible clones for the Arduino Leonardo available, including the Seeeduino Lite and the Pololu A-Star 32U4 Prime LV. The transmission and reception pin is 17 and 24. The circuit utilizes a total of 23 digital pins, excluding the three digital pins present on the ICSP header, which are unique and not duplicated.
The microcontroller used in uno is ATmega328. Robotistan Leonardo Project Development Kit - Compatible with Arduino and 4000+ products for makers at. You can learn more about the specifications of the Arduino Leonardo here. The microcontroller used in Leo is ATmega32u4. The board has 14 digital input/output pins (of which 7 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB micro B connection, a power jack, an ICSP header, and a reset button.
This article focuses on the Arduino Leonardo, a micro. Since no secondary USB-Serial converter IC is required, you can easily use the Leonardo to emulate arbitrary USB devices, such as a keyboard or mouse. Arduino is both a micro-controller and micro-controller kit that enables you to control hardware devices using C, a programming language. The Arduino Leonardo employs a single ATMega32U4 MCU with a USB interface baked right in.
