What kind of power supply does an Arduino Nano use?

What kind of power supply does an Arduino Nano use?

The Arduino Nano can be powered via the Mini-B USB connection, 6-20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source.

How does the reset button work on the Arduino Nano?

Rather then requiring a physical press of the reset button before an upload, the Arduino Nano is designed in a way that allows it to be reset by software running on a connected computer. One of the hardware flow control lines (DTR) of the FT232RL is connected to the reset line of the ATmega328 via a 100 nanofarad capacitor.

What kind of bootloader does Arduino Nano use?

The ATmega328 on the Arduino Nano comes preburned with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. It communicates using the original STK500 protocol.

How does the Arduino Nano work with ATmega328?

Select “Arduino Duemilanove or Nano w/ ATmega328” from the Tools > Board menu (according to the microcontroller on your board). The ATmega328 on the Arduino Nano comes preburned with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. It communicates using the original STK500 protocol.

How many pins are there on the Arduino Nano board?

Of the 30 pins available on the Nano board, 22 pins are associated with input and output. In that 14 pins (D0 to D13) are true digital IO pins, which can be configured as per you application using pinMode (), digitalWrite () and digitalRead () functions. All these Digital IO pins are capable of sourcing or sinking 40mA of current.

Is the Arduino Nano based on a microcontroller?

Apart from that, the layout of Arduino Nano is very much self-explanatory. Regarding the pin, I will discuss about them in the Arduino Nano Pinout Section. As Arduino Nano is also based on ATmega328P Microcontroller, the technical specifications are similar to that of UNO.

What’s the difference between Arduino Uno and nano?

After Arduino UNO, the most popular board in the Arduino line-up is probably the Arduino Nano. Both UNO and Nano are based on ATmega328P Microcontroller but Nano is significantly smaller in size compared to UNO. Despite the size, Arduino Nano packs in more or less the same features as UNO.
