## Questions & Answers

**Q: I'd like to dd a GPS module to this, which is the smallest and best option I hve?**
A: Look into Adafruit GPS modules compatible with the arduino. I know they have shield GPS modules for the uno so you can probably find an unshielded version to use on the micro. Basically go to adafruit.com and take a look. They also helped design the micro so best chance for compatibility.

**Q: What are the dimensions (and weight) of the board?  Amazon only seems to list the packaging dimensions.**
A: From the Arduino web sitec  http://arduino.cc/en/Main/ArduinoBoardMicro   "The maximum length and width of the Micro PCB are 4.8cm and 1.77cm respectively, with the USB connector extending beyond the former dimension."  Height about 20mm (defined by header pins) Weight 7 g. Also check out the Nano board.

**Q: does it have the I2C bus ?**
A: Hi, yes!  Here is a tutorial with more info: http://tronixstuff.com/2010/10/20/tutorial-arduino-and-the-i2c-bus/

**Q: is this as powerful as the Arduino mega?**
A: Simply, no. But powerful for its small size.

## Customer Reviews

### ⭐⭐⭐⭐⭐ good
*by J***N on April 12, 2025*

good. I always like these arduino boards.

### ⭐⭐⭐⭐⭐ So powerful in such a small size
*by J***E on July 20, 2014*

I love anything and everything Arduino, I love the micro because it is a small 17 pin long board that fits on all of my breadboards. It is really helpful that it has the regular arduino voltage regulator on it so that I can use all my normal power supply. I was amazed when I locked at the pin layout because so many of the pins have multiple purposes. Some of the I/O pins also work as analog pins and PWM pins. It has a total of 6 Analog in pins (That is the same as the uno!). I love that it uses the same programming environment and I can upload all my codes to it. The one odd thing is that it doesn't come with a cable to write to it, which wasn't a problem for me because it is a pretty standard port, just make sure it is a data cable (not just a charging cable). Overall, I love it. It works perfectly and fits the small form factor that I need sometimes.

### ⭐⭐⭐⭐⭐ Authentic Arduino at a reasonable price
*by M***Y on January 9, 2015*

This is the real deal, if you are looking for an authentic Arduino in a very small package this is the board you want. As stated in other reviews this board very identical to the Leonardo board except it is much smaller. The device works to emulate keyboard/mouse input which is what I needed it for and the quality of the board and solder joints is as good as you can get. This seller is also selling these at a much more reasonable price compared to others I have seen, beware of others that have a similar price but then charge almost the same amount for shipping which almost doubles the cost of the board. The free shipping this seller offers (without the need for a minimum purchase) makes this the best deal I could find. I only wish I could find one for a reasonable price that doesn't include the headers.
