The Arduino Leonardo is a microcontroller board based on the ATmega32u4 (datasheet). It has 20 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. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.
The Leonardo differs from all preceding boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.
This is an Arduino Compatible board. It is NOT an original Arduino board, but is similar. None of the Arduino Leonardo boards sold on the internet at this price are original, they are all copies. This is perfectly legal, seeing that the whole arduino ecosystem is open source! Please note this board is not manufactred by Modtronix! We do not have control of the brand and quality of components used! We have however carefully selected suppliers that consistently supply quality products. For boards using durable, brand name components, also have a look at our own "Manufactured by Modtronix" range of SBC and accessory boards.
We stock a wide variety of Arduino compatible sensors, modules, shields and other accessories. Seeing that this is a 5V board, all accessories must be 5v compatible! Browse our menu at the top of this page (or use search box) for our full range of accessories. Following are some lists (created by search terms) of compatible accessories.
