Like the Nano, the Micro's size and male pin headers make it perfect for prototyping with a breadboard. However, Arduino also offers this board without headers pre-soldered.

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 ...

Pin 2 on the Arduino schematic is really GPIO2 on the NINA, therefore it should not be labeled GPIO34. This is confirmed by the fact that the pin numbering on the Arduino schematic matches the pin ...

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.

The Arduino Nano Connector Carrier is a compact add-on board designed for the Arduino Nano boards to allow easy connection to Qwiic, Grove, and Modulino expansion modules. The company also announced ...

The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.
