Product Description

Pro micro

Description

  • The ProMicro 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.
  • This tiny little board does all of the neat-o for for 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 for 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.

    So far it works perfectly. Note that I have done a bunch of arduino stuff on my computer before this so I may already have drivers that other people don't have installed.Connected to my computerOpened Arduino IDE and loaded Blink sketchSet board to Leonardo and selected the appropriate COM port (It showed up in the list already identified as a Leonardo)Connected an LED to pin 9 and modified the sketch accordinglyHit upload and within a few seconds I had a blinking LEDNote that for some reason the onboard red Rx LED keeps flashing even after the upload, not sure why. I unplugged it from the computer and connected to the battery pack I used for charging my phone on the go and it started back up with no issues and without the red light blinking. So it does appear to be getting some sort of continuous data signal when plugged into my computer which is odd, but doesn't seem to actually be a problem.The pinout appears to match the sparkfun pro micro board for which I've attached the diagram. EDIT: I just realized that the pins with the white circles around them are the PWM pins.

    5.0 out of 5 stars Works great but...
    Reviewed in the United States on April 16, 2019
    As with most all clones these days you have to be prepared to work a little bit to get what you want. Frequently these will throw a "USB Device not found" error. Fire up your Arduino IDE, open any known good sketch, connect your board, select "Leonardo" in the IDE, put a jumper wire on pin RST and get ready. Click UPLOAD on the IDE, and when the program switches from COMPILING to UPLOADING, ground the jumper 3 times quickly. The IDE will see the board, assign the COM port and from there it works fine. If you get everything working and the red TX LED stays on, just put a "TEXLED0;" in your sketch, that turns off the LED. The photo is this exact board running a temperature gauge sketch.
