- Leonardo with Headers [A000057] - ATmega32U4 Microcontroller, 16MHz, 20 Digital I/O Pins, 7 PWM, USB HID Support, Built-in USB Communication, Compatible with Arduino IDE for Custom Projects

This board is an excellent choice for custom projects that need direct USB communication. The ATmega32U4 chip makes it stand out because it can act as a keyboard or mouse without extra libraries, which opens up a lot of creative possibilities. With 20 digital I/O pins, 7 PWM outputs, and multiple analog inputs, there is plenty of flexibility for sensors, LEDs, and control devices. The headers are sturdy and make prototyping easy on a breadboard or with jumper wires. Running at 16MHz, it is fast enough for most hobby and DIY applications. Setup with the Arduino IDE was seamless and sketches upload quickly over USB. The board has been reliable during testing, and the small size makes it easy to embed into projects. A great microcontroller for makers who want more functionality than a basic Uno while still keeping full compatibility with the Arduino ecosystem

The board comes certified Arduino built in Italy, so it is legit. The boarditselfisamazing. Compared to the bread and butter UNO R3, this board is much smaller of a profile then the UNO. The MicroUSB is so convent and nice to have. It slims down the overall profile of the board and means I now have more options for cables and so forth. The old giant ATMega is gone replaced instead by a much more robust ARM based processor. The chip itself is of the SMD tech, which you can see in they turns of the item. The board came shipped in a little box, but other then that, which isn't about the item and more of shipping/retailer then the board. I would recommend this board as it is the same board as the UNO but half the weight and with more compatibility options. Overall fantastic purchase and I would highly recommend this product to any and all persons interested in the related fields. UPDATE: I have successfully fried this board, rather easily I might add. However! One can not downgrade the product due to user error, and for that I still think the board is amazing. Even though all my digital pins are toast, the MicroUSB connection makes it a hell of a power supply. Just use a wall wart and use the Vin pin or the 3.3V & 5V pins to power your projects. The MircoUSB alone makes the whole product worth it in my opinion. Because I have several devices that utilize the MircoUSB connection, finding a wall wart to power this thing is effortless.

Legitimate product. Easy to set-up. Works great for Pokemon Automation Bot.

A friend asked if I would automate a room-sized model railroad he wanted to build in his house, so I bought one of these to start developing code on my small test track. I'd never worked with Arduino before but have experience developing C (and Python) code, so working with this card has been super easy, and it works great for this application. My only regret is not buying a Mega instead, as even on my small setup I quickly ran out of pins.

This is an excellent Arduino Leonardo with Headers. I bought two of them for my robot projects. I'm glad I found them because they are hard to get. I had some old robot projects that required the Leonardo. So, I'm very happy to get them at this low price. I inspected both of them very carefully. They were in perfect condition.

I gave this arduino three (3) stars because I also bought some that were non-brand that worked just as well (if not better) and didn't have such a high price tag. These seemed to have a problem with some of the PCs I was working with. It's good thing I had Windows 10 and not just Ubuntu for programming, otherwise I would have been out of luck for it to work.

Love this thing. All of the Arduinos are great products. This is a genuine arduino Leonardo. The pre-soldered headers are nice, although if you are decent with a soldering iron, they are 0.1" headers, so it can be done if you already have the headers and order the version without. I have been programming microcontrollers for several years, and the Arduino is a great platform for bringing up a circuit quickly and trying out new concepts, without the fuss of creating a complicated project that is required of other traditionally microcontrollers for programming. This would make a great gift for someone who loves to play around with electronics, and even those in school looking to get started with electrical concepts.

I bought this board to upgrade my handbrake because the board that comes with the sim handbrake delay the input even when I adjust the sketch it still delayed. So I decided purchase this board and it's amazing, this board executive the sketch very quickly....it made me fall in love with my handbrake now. Great board for your handbrake sim upgrade mod

Arduino Leonardo は、ほとんどが Arduino Uno と同じ構成で使えて、さらにパソコンに接続した状態で、マウスやキーボードの代わりにもなる便利なボードです。つまり、他のスイッチやハードウェアをつけなくても単体で遊べる範囲が多いのが特徴です。 Arduino を紹介した多くのページでは、Arduino を USBに接続すると自動的にドライバの組み込みがされるように書かれてますが、2/12にダウンロードしたIDE環境「Arduino 1.0.5-R2」＋ Windows 7 の場合は、そうではなかったので、少し補足しておきます。参考になる人がいれば幸いです。 1.Windows 7 でのドライバのセットアップ方法 1.1 「Arduino 1.0.5」を展開したフォルダの「drivers」フォルダにある「Old_Arduino_Drivers.zip」を展開して、中にある「Arduino Leonardo.inf」を「drivers」フォルダの中に書き出します。 1.2 Windows 7 が 32bit版なら、dpinst-x86.exe を実行し、ドライバをインストールします。 64bit版なら、dpinst-amd64.exe を実行します。 1.3 そののちに Arduino Leonardo を USBに接続すると「Arduino Leonardo」がきちんと認識されるようになります。 2.ボード単体で遊べるスケッチ (サンプルコード) 「01.Basics」＞「Blink」「Fade」で、ボード上のLED点灯を試せます。 「04.Communifation」＞「PhysicalPixel」は、IDEの「ツール」＞「シリアルモニタ」を開いて、H, Lという文字を送信することで LEDのオフ・オンをコントロールするデモ。 「05.Keyboard」＞「Keyboard」＞「KeyboardMessage」も同様にシリアルモニタ上で入力した文字を書き換えるデモ。 プログラムコードはシンプルなので、プログラムに振れたことがある人なら、誰でも簡単に動きを理解することができるのではないでしょうか。

Ho scelto il Leonardo come primo Arduino quasi per caso, dato che non avevo esperienza con la piattaforma ed alla fine si è rivelato adatto ai miei scopi, perfino più del "tradizionale" UNO. + seconda porta seriale a disposizione; + i piedini digitali non sono connessi in parallelo al connettore ISC quindi restano più piedini disponibili quando si usano gli shield; - usa il cavetto USB micro che non è molto diffuso; - la connessione USB è un po' instabile per le continue sconnnessioni e riconnessioni; - il chip è saldato sulla scheda per cui non si potrà usare per programmare un chip da montare poi su uno stampato standalone, che potrebbe risultare comodo per gli utenti avanzati; - ho avuto problemi nell'utilizzo di un ethernet shield w5100 non originale, devo ancora capire se dipende dal Leonardo o dallo shield difettoso.

Das Arduino Leonardo mit Headers bietet die gewohnt hohe Arduino-Qualität und ist ein sehr gutes Produkt, besonders für Projekte, die Tastatureingaben am Computer simulieren sollen. Ich nutze es genau für diesen Zweck, und die Umsetzung über das USB-Kabel ist unkompliziert und benutzerfreundlich. Dank der integrierten USB-Schnittstelle funktioniert das Board hervorragend, um Tastatureingaben, Mausbewegungen oder andere HID-Anwendungen zu steuern. Für alle, die an interaktiven Projekten arbeiten, bei denen der Computer direkt gesteuert werden soll, ist das Arduino Leonardo eine großartige Wahl!

el packaging un poco desastroso porque viene en un sobre apretado son protección excepto la caja del propio arduino, por lo demas genial.

Its so good but i asked for a redraw before i got the iteam
