The Arduino Pro Micro Atmega32u4 is a small, breadboard-friendly microcontroller board. It has an operating voltage of 5V and a clock speed of 16 MHz, making it suitable for a wide range of applications. The ATmega32U4 microcontroller has 32KB of flash memory, 2.5KB of SRAM, and 1KB of EEPROM, and features built-in USB support, which eliminates the need for a separate USB-to-serial converter. The Arduino Pro Micro has several digital and analog input/output pins, making it easy to interface with sensors, actuators, and other components. It is commonly used for DIY electronics projects, hobbyist inventions, and educational purposes, and is ideal for projects that require a compact and low-cost microcontroller board.

9 channels of 10-bit ADC, 5 PWM pins, 12 digital I/O as well as hardware serial connections Rx and Tx. Running at 16MHz and 5V, this board will remind you a lot of your other favorited, Arduino-compatible boards, but this little guy can go just about anywhere.

There is a voltage regulator on board which can accept a power supply of 6-9VDC (max. 10V). Make sure to connect the input voltage to the RAW pin and not VCC (5V).

The Pro Micro Arduino compatible board is originally developed as open hardware by the company Sparkfun. It comes with the Atmel Atmega32u4 MCU and runs with 16MHz. A pair of pin headers are included, as shown in the picture.

    This is a Pro Micro clone, built with the same 32u4 chip that’s in the original (and the Leonardo, among a couple of others). The beauty of the 32u4 is that it has USB built into it in such a way that in addition to serial communication and programming, you can get it to act like a keyboard or mouse (there are Arduino libraries to do this).

    Worked right out of the package, pins soldered on nice and clean, and the LEDs are bright. I’m currently using it to read when a switch is closed and then act like a mouse to do a whole bunch of left-clicks to gather stuff in a game I play.

    I bought this when it was $7.75 which is a pretty good price, especially considering that it only took a few days to get here. I see it’s $6.90 now, which is a great price!

    To simulate mouvements and clics from a mouse only by pushing once on a push-button. Can simulate keyboards typing too.

    Clean looking, everything is soldered on nice and straight, except for the headers that aren’t soldered at all, but come as an option, which i appreciated. Had some issues connecting the board to a serial moniter in xubuntu, however windows 7 works like a charm. (Xubuntu gave me a bunch of errors along the lines of cannot connect to /dev/ttyacm0 device is busy, but would eventually connect if you tried enough times) btw great customer service too!

    As advertised, shipping was faster than advertised, packaged well, works great

    This thing is smaller than I expected! I honestly thought this was the 6 axis gyro I intended to attach to this tiny thing. I plan on building a EDTracker with this board. It will act like a TrackIR, but have a little bit lower latency and a higher reliability.The Pro Micro 5V is built well, with all pads appearing to be well soldered to the board. The PCB is a little rough around the edges and could use a bit of sanding to look smoother; but isn’t that important, as most people will be putting their final build into a box/case/housing of some sort. The free ‘Non-Prime’ shipping was pleasantly fast, and was well packaged using static safe envelopes.

    Definitely operates fully within Arduino specs. I ordered some Chinese imitations that really let me down. Their clock speed was four times slower than it was supposed to be, didn’t hold the memory it was supposed to. It was a wreck. The CANADUINO works exactly as it should. And it got here SO much faster than the Chinese ones. This is my go to from now on.

    I use this for a remote pendant on my cnc router with no issue.
