The Micro is a microcontroller board based on the ATmega32U4, developed in conjunction with Adafruit. 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, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a micro USB cable to get started. It has a form factor that enables it to be easily placed on a breadboard. The Micro board is similar to the Arduino Leonardo in that the ATmega32U4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Micro to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.

Here at SparkFun, we refuse to leave 'good enough' alone. That's why we're adding to our line-up of Arduino-compatible microcontrollers once more! The Pro Micro is similar to the Pro Mini except with an 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.
When either of these cases happens, the device manager is not able to recognize the device and is usually seen as an "unknown device" when the microcontroller runs the sketch. There are ways to recover the an Atmega32U4 (i.e. LilyPad Arduino USB - Atmega32U4 board, FioV3 - Atmega32U4, Pro Micro 5V/16Mhz, Pro Micro - 3.3V/8Mhz, etc) if this happens. Check below for more information:
You can try the double reset method by tapping the RST pin to GND twice (since there is no reset button on the board) as explained in the Troubleshooting sections labeled as Reset to Bootloader and How to Revive a "Bricked" Pro Micro => -micro--fio-v3-hookup-guide/troubleshooting-and-faq.
I have been using this board for some years now, various projects from logging/monitoring to replacement washing-machine controller. I was using it with an older Arduino IDE (1.6.3) and older board defs for all that time, with no trouble (except the delay caused by ModemManager - ubuntu 14.04). After updating OS and IDE to the newer version with the boards-manager in it, the newer board defs define the board as ProMicro with the difference between 5V,16Mhz and 3.3V,8Mhz being on a separate menu, with a default of 3.3V. This makes it WAY TOO EASY to write the wrong settings to the promicro, would be much harder to get wrong if they were still separate boards rather than defined as different processors. Needless to say, I bricked the Promicro when I wrote a 3.3V program to a 5V board. Or did I?starting upload from the ISP before plugging the board just complained that there wasn't a port there, pressing it as I plugged in took too long before starting the upload and the port was already gone.
so I found the avrdude bin in the arduino program folder, built the blink example and found the .hex file in /tmp, made a one-line script with an avrdude command to write blink.hex to /dev/ttyACM0 and hovered over the enter key as I plugged in the promicro. I got the timing just right and the led started to blink :)
There is some problem with USB serial!I have Arduino IDE v1.6.5 and trying to convert my micro to ArduinoISP with sketch from examples. It compiles well but isn't work with avrdude!$ avrdude -C c:/temp/avrdude.conf -patmega328p -b19200 -cavrisp -Pcom22 -U flash:r:test.hex -v -vavrdude.exe: Version 6.0.1, compiled on Apr 15 2015 at 19:59:58 Copyright (c) 2000-2005 Brian Dean, Copyright (c) 2007-2009 Joerg Wunsch System wide configuration file is "c:/temp/avrdude.conf" Using Port : com22 Using Programmer : avrisp Overriding Baud Rate : 19200avrdude.exe: ser_recv(): programmer is not respondingavrdude.exe: stk500_recv(): programmer is not respondingavrdude.exe: stk500_getsync() attempt 1 of 10: not in sync: resp=0x03I cheked it with PuTTy and "Serial Monitor" by sending "1 "(one and space). It respond with "AVR ISP" and this looks nice but then I tried to do the same using HTerm and it gave no reply!I checked what happened with SysInternals PortMon and discovered that neither HTerm nor avrdude sets SERIAL_DTR_CONTROL. So I downloaded source of avrdude:
This is a really awesome board. Arduino compatibility, native USB and a sleek profile make it great for many projects. I have never had any trouble getting it to work, contrary to many comments below. My one complaint is that the USB receptacle is too flimsy (a common problem with surface-mount micro USBs). After plugging / unplugging a USB cable a dozen or so times, even quite gently, the receptacle breaks off, pulling the solder terminals off with it. Although I appreciate the design choice to make the size as small as possible and the back of the board flat, a device whose main feature is native USB should have a sturdier USB receptacle.
Like many here, I had some issues getting the Pro Micro to connect to my Windows 7 Arduino IDE environment. I believed I had installed all of the code bits as far as drivers and the Arduino IDE, but I just could not get it to work. Somewhat in desperation, I wired up the reset button suggested to see if I could force the board into the mode I wanted. Lo and Behold! Forcing the Pro Micro via a reset caused Windows to recognize it differently, than it did when not in download code mode and attach the appropriate drivers. Now it works just as well as the Uno R3 does, with both code downloads and serial monitoring from the Arduino IDE flipping back and forth just as you would like. I have not used the reset button again except for that one time driver install.With regard to the micro USB port weakness issue, I think I have "fixed" the problem by simply connecting a USB cord to it once and leaving it in while I am in development. Forewarned is for armed. I disconnect the PC end when I need to power down or disconnect it.My first project ported very easily from the Uno R3 to the Pro Micro - although I did use a completely different set of pins from one to the next. This demonstrates the value of defining constants for which pin you are using at one place in your code - it makes this sort of transition trivial. The Pro Micro appealed to me for the small form factor, USB connectivity (just in case I need to later easily tweak the software), and on board power regulation. I may play with power regulators next to learn how to do this on my own.
How many mA does this draw at maximum load? I'm trying to decide what battery and charger to get to combine this with an OpenLog (6mA) and MPL3115A2 (40 microAmps). They're going to need to collect data for several hours (anywhere from three to five).
I have "SparkFun Pro Micro 5V/16MHz" selected, but the IDE does mention it can't find a Leonardo selected when something (else) goes wrong.I installed the drivers as directed here: -micro--fio-v3-hookup-guide
There is an issue with the Arduino serial monitor and some PC/Leonardo/pro micro connections. The serial monitor will send data but will not receive!A work around is to use a third party terminal. I am using putty.It's a bit of a PITA as you have to manually exit the terminal to release the com port for uploading. But it is better than staring at the serial monitor and wondering what is going on.
I love this little board..... but word of caution, the micro usb pulls off kind of easy, be very gentle. It would be nice if SF could used vias as the usb footprint pads for added strength which is how we do it where i work for heavy use applications.
For anyone working with windows 8/8.1 here is how I got it to work:
- Enable installation of unsigned drivers: 8.1 or 8
- Once signing is disabled uninstall and re-install the arduino IDE (version 1.0.5)
- Open device manager
- Get the windows drivers from the tutorial
- Reset the board twice quick succession as described under Reset Bootloader
- Notice the windows sound signalling a new device being recognized. The new device should show up in device manager with the orange triangle as the pro micro.
- Install the driver as described in the tutorial for windows installation for this new device that showed up. I had to reset the board a couple of times during navigation to the driver and then just as I was clicking the button to install the driver. It finished before I heard the sound signalling removal of a device.
- Upload sketches to the regular com port that is under device manager, and during upload the pro micro will show up briefly in device manager with the driver you just installed, and disappear, and the sketch should work.
