The A-Star Primes are based on the same ATmega32U4 AVR microcontroller as the Leonardo and ship with Arduino-compatible bootloaders, so they can be used a direct substitutes for the Leonardo in typical applications. The table below compares the Arduino Uno, Leonardo, and our A-Star 32U4 Prime controllers. See this forum post for more information. Warning: We recommend not connecting the Arduino to USB while it is powered through VIN. Note that the Leonardo only works with the Arduino IDE version 1.0.1 or later. More information about the Arduino Leonardo is available on Arduino’s website. breadboard, sensors, jumper wires, and LEDs) that make it possible to create a number of fun introductory projects.

Note that we also offer a SparkFun Inventor’s Kit, which includes an Arduino Uno along with an assortment of components (e.g. you can easily make your Arduino wireless with our Wixel shield), making it a great introductory platform for embedded electronics.

The Arduino has a large support community and an extensive set of support libraries and hardware add-on “ shields” (e.g. See Arduino’s getting started page for more implications of the Leonardo’s single-MCU design. This makes the Leonardo more versatile: in addition to supporting a virtual (CDC) serial/COM port interface, it can appear to a connected computer as a mouse and keyboard. The Leonardo differs from all preceding Arduino boards in that the user-programmable ATmega32U4 AVR microcontroller has built-in USB functionality, eliminating the need for a secondary processor. This board ships with the power jack and through-hole headers soldered in, as shown in the product picture. It contains everything needed to support the microcontroller simply connect it to a computer with a Micro USB cable or power it with a AC-to-DC adapter or battery to get started (USB cable and power supply are not included). It has 23 digital input/output pins (of which 7 can be used as PWM outputs and 12 can be used as analog inputs), a 16 MHz crystal, a USB connection, a power jack, an in-circuit system programming (ICSP) header, and a reset button. The Arduino Leonardo is a microcontroller board based on the ATmega32U4.

#ARDUINO LEONARDO BOARD SERIAL#

The Leonardo works with our motor and robot shields, and it works with our Wixel shield in a limited capacity: the wireless serial features work, but the wireless reprogramming does not. As such, there could be incompatible Arduino shields and libraries. It contains everything you need to support the microcontroller: to get started, you just have to use the USB cable to connect it to a computer or power it via 12VDC power supply or battery (not included).Įxpansion shields are available to expand the communication and processing capabilities of the Arduino board.Note: There are differences between the Leonardo and previous Arduino boards. It has 20 digital input output pins (7 of which are PWM-out and 12 usable as analog inputs), a 16 MHz oscillating crystal, a USB Micro B socket, a network socket, an ICSP header and a reset button.

It also allows, thanks to the direct USB connection and independent physical serial, the use of the TX and RX PINs of the shields independently of the arduino ↔ PC communication, allowing them to be used in devices that must communicate at the same time via serial and with the PC as in the case of home automation and automation BUS.

#ARDUINO LEONARDO BOARD CODE#

The ATmega 32U4 microcontroller USB manager for connection allows access to code libraries that allow the card to mimic keyboard, mouse and other devices that use the USB-HID protocol. Leonardo is the first Arduino development board to use a microcontroller with integrated USB.
