Overview

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. It also has other implications for the behavior of the board; these are detailed on the Getting started with the Arduino Leonardo.

Dev board return policy

Development boards are specialty items that generally cannot be resold on return, especially if the firmware has been flashed. Defective boards can be replaced or returned for refund within 30 days of purchase. Non-defective boards can be returned in the same time frame if in like-new condition with a 20 percent restocking fee applied. If the board has had altered firmware or became bricked due to a non-standard firmware flash, the board may not be eligible for return.

Sales tax is required in many states and will be added at checkout if applicable to your delivery state. Tax exempt forms can be sent to our support department.

Bulk/High Value Order Returns

Due to the labor required to package and ship bulk orders, as well as cost and stock issues involved in replenishing items, bulk orders of 5 pieces or more are not returnable unless the equipment is defective or mis-advertised, or a return period is prenegotiated. For non-defective returns over $500, a restocking fee may be deducted from the refund to cover bank or card processing fees.

Items on backorder or preorder will ship as estimated on the item page. You can cancel an order any time up until shipment. Orders with expedited shipping will arrive in the advertised time after the order ships, not after the order is placed.
