Description: 1. The Pro Micro is similar to the Pro mini except with a ATmega32U4 on board. The USB transceiver inside the 32U4 allows us to add USB connectivity on board and do away with bulky external USB interface. 2. This tiny little board does all of the neat-o Arduino tricks that you're familiar with: 4 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as hardware serial connections Rx and Tx. Running at 16MHz and 5V, this board will remind you a lot of your other favorite Arduino-compatible boards but this little guy can go just about anywhere. If you're supplying unregulated power to the board, be sure to connect to the "RAW" pin on not VCC. Features: ATmega32U4 running at 5V/16MHz Supported by Arduino IDE v1.0.1 On-Board Micro-USB connector for programming 4 x 10-bit ADC pins, 12 x Digital I/Os Rx and Tx Hardware Serial Connections Note: 1.When you open the Arduino IDE software, pls go to the tool and choose the board "Arduino Leonardo" 2.The acceptable voltage range is 5 to 9 V.Package included: 3* Pro Micro ATmega32U4 5V/16MHz Development Board Review: All three units functioned well. At first, I had a problem with my old Windows 7 computer recognizing the device. I was able to upload a sketch to it, and once I had done that, then the computer located the proper device driver for it. Not sure how that worked, but it did. They all worked fine with a Windows 10 computer. I was able to run a few simple programs, including one emulating a USB keyboard. One thing to note, when writing a sketch to output to the UART, you must use serial1.begin() (and associated serial1.xxx functions) not serial.begin(); The USB port does NOT share the UART pins as is the case on a UNO. If you have code that writes to the USB port, the program will not run until you open the serial monitor. If you write to the UART, it will run regardless of whether you have anything connected to the USB port or UART pins, but the output will only go to the UART pins. Review: Shipping was great on this item - arrived very quickly (UK). The boards are individually sealed in anti-static bags, with the header pins included but not soldered, which leaves your options open. I have now tested all 3 boards and they work fine with the Arduino IDE. It's a versatile little board and good value here - I highly recommend to others. Installing the driver can be a little confusing at first, but is straightforward. I have documented some instructions below to help other users: (1) Download the Arduino IDE (2) Plug the Pro Micro board into your computer. If the COM port does not appear in the COM port list in the Arduino IDE (go to Tools--> Port -->), the chances are you are using a charging USB cable, rather than a data USB cable - so use a cable you know works and communicates with other USB devices. (2) If you are happy with the USB cable, but still don't see the COM port In Windows, open Device Manager and navigate to Ports (COM & LPT). It should read something like 'Arduino Leonardo' (this is how the board is recognised by Windows). If things aren't working, there will be a yellow exclamation mark besides the Arduino Leonardo text. Right click on this and select "Update Driver Software" and "Browse my computer for driver software". Browse to your Arduino installation directory, something like "C:\Program Files (x86)\Arduino", make sure "subfolders" is ticked. Click OK and the driver should install (it can take a while). (3) In the Arduino IDE you should see a new COM port available (under Tools) - if not try restarting the Arduino software and confirming the "Arduino Leonardo" device appears in Device Manger without a warning exclamation mark. (4) You are now ready to upload sketches from the Arduino IDE! Try the "Blink" sketch first (File--> Examples--> 01.Basics--> Blink). Of note, the Pro Micro board (unlike other boards) doesn't have a builtin LED so the sketch will upload okay, but you won't see flashing. It has two LEDs that can be flashed, so try changing instances of LED_BUILTIN in the Blink sketch to 17 (RX LED) or 30 (TX LED). Upload the sketch and you should see some flashing!

Ils fonctionnent tous avec un firmware QMK (firmware de clavier mécanique) comme tout bon Arduino pro micro, faut juste voir combient de temps les ports USB vont tenir en utilisation quotidienne.

Der Arduino funktioniert sehr gut. Ich verwende ihn um ihn als USB Tastatur an meinen Rechner anzuschließen. Mit den Beispielen der Arduino Bibliothek funktioniert das wunderbar. In Verbindung mit einem 433 MHz Funkmodul habe ich ihn auch getestet. Das Funktioniert ebenfalls sehr gut (die Funkt verbindung reicht durch das ganze Haus). Er ist zwar etwas teurer als die Arduino Nano nachbauten, die ich sonst meistens verwende, aber diese Funktionieren nicht als Tastatur, daher habe ich für dieses Projekt den Pro-Micro verwendet. Ansonsten sind die Unterschiede zum (etwas billigeren) Arduino Nano glaube ich nicht sehr groß. Fazit: - Funktioniert sehr gut - Lässt sich als Tastatur oder Maus am Computer anschließen - Sehr ähnlich zum Arduino Nano, aber für manche Projekte funktioniert nur dieser hier (oder ein noch größerer und teurerer) - Ich kann den Mikrocontroller wirklich nur empfehlen

Totalmente compatibles con el original de Arduino Micro, están bien fabricados y bien embalados, cada Arduino en su sobre antiestático. Las filas de pines vienen sin soldar, tal como muestran las fotos en el anuncio, lo que es muy útil si se van a utilizar en un montaje de cableado directo, porque es mucho más fácil soldarlos que des-soldarlos, si fuese necesario.
