Despite the differences in size and microcontroller, the Arduino Nano and Micro share some similar pinout configurations. They both have two GND pins, two reset pins, one AREF pin, and three power ...

The Arduino Nano was used for this demonstration as it has 5 volt GPIO pins and the lasers are 5 volt as well - so easy to wire up. Also, the lasers consume about 10mw each, which is just under the ...

This is confirmed by the fact that the pin numbering on the Arduino schematic matches the pin numbering on the datasheet. In fact, even the label names partially match but the GPIO numbering is ...

Arduino has announced a new line of Nano boards that will begin shipping next month. From the design, to the chips and features on the board, to the price, there’s a lot that is new here. I s… ...

While the pinout is very similar to the Arduino Nano’s, there are four (12-bit) analogue inputs rather than eight (10-bit). Some digital GPIO pins are numbered differently too.

Considering that the Uno is much larger than the Nano, you might think it comes with a lot more pins. However, their pinouts are surprisingly similar in most aspects.
