Diymore Pro Micro AT-me ga 32U4 5V /6MHz Bootloader Type C Leonardo Development Board Microcontroller with Pin Header for Arduino Compatible

worked perfectly clean circuit board with clear reference print easy to connect to PC and program

These can emulate keyboard and mouse

The boards I received are clocked at 16mhz but VCC is regulated to 3.3V not 5V as advertised. Not a big issue for me as I plan to run the project from USB so if I want 5V operation I can just jumper VCC to RAW and if I don't, well they seem stable enough at 16mhz on 3.3V so I might just leave it.

This Pro Micro board has an Atmel Mega32U4 chip, and seems to be nicely made, it looks like a quality board in terms of PCB and soldering of the components. I like that it's so nice and compact, and it worked perfectly for me in Arduino IDE set up as a SparkFun Pro Micro board. No complaints.

Neither of these worked when I tried them.

I use these all the time for small electronics projects. These worked well and programmed first time without issues. The USB port seemed soldered on well, which can be an issue. No problems running these and they are working well. The pin headers were not pre soldered but I prefer that as I don't usually use them and prefer to solder wires directly. I didn't have to remove them which was nice.

These seem well built, and plug in and out nicely. Voltage regulator seems to work as it should, functioning on my 12v input has worked. The processor is soldered on upside down Vs the reference, but I don't believe this seems to make any issue. Clearly, this is a clone of the SparkFun version, not an original, which is reflected in the price - reasonable in comparison to the market. All in it's a good clean clone that works as it should. Do note that this doesn't work with USB-C>C cables.

The small size is great. Please check the capabilities; I tried to use one of these for a wireless RGB desk lamp, and failed because it couldn't drive three independent PWM signals (red/green/blue) while simultaneously decoding 433MHz ASK using VirtualWire.

Me ha venido miy bien por su tamaño sin renunciar a nada de potencia, esta placa tiene todo lo que necesitaba para hacer una pequeña herramienta que interactuaba con el usb del ordenador. Este microcontrolador va montado en una placa de muy reducido tamaño. La he programado miy facil con el IDE de arduino y he podido aprender de infinidad de tutoriales de internet que casi tienen el codigo que necesitas. Relacion calidad precio aceptable, volvere a comprar si me hace falta.

Leider ist der Board tot. Ich habe es an zwei Rechner probiert und bei beiden Rechner auch unter Win11 und Linux Mint 22.1 ausprobiert kein Reaktion vom Board. Alle meine andere Arduinos sind problemlos ansprechbar.

I was hoping to replace my old broken boarf with this but it arrived with a dead chip. I geuss its just a lottery if you get one that works

La carte fonctionne alimenté par l'USB mais pas avec une alim 5V externe connecté sur le VCC et les GND du bas: le GND du haut correspond au GND de l' ATmega32U4 et les deux du bas au UGND (GND de l'USB) mais ne sont pas relié dans la carte. Un connexion externe des GND est donc nécessaire pour une utilisation mixte USB et 5 V externe ou utilisation du GND du haut: le UGND de l'ATmega étant alors en l'air mais comme on est en différentiel (D+ D-) cela marche..

This board is sold as a 5v board, in reality it's 3.3v
