Arduino Nano Every Specifications/Functions

In this article, we will explain in detail the specifications and functions of Arduino Nano Every.

The Arduino Nano Every is an even smaller Arduino board compared to the Arduino Micoro. It can be used by inserting it directly into the breadboard.

The previous product "Arduino Nano", with the same shape and footprint as the Arduino Nano Every, is also currently available, but with lower performance and higher price.

For more information on the specifications and features of the Arduino Nano, please refer to the following article.

①Microcontroller(Microcomputer)

The microcontroller of Arduino Nano Every uses “ATmega328P” from Microchip Technology(USA).

A microcontroller is a very important component in controlling electronic devices that correspond to the human “brain”.

In addition, various memories such as SRAM, Flash memory, and EEPROM are also built into the microcontroller.

②USB Port

By connecting the Arduino Nano Every to the USB port of your PC with a USB cable, you can communicate between the Arduino Nano Every and your PC.

Programs (sketches) created on the PC can be written to the Arduino Nano Every, and the Arduino Nano Every can be controlled from the PC via serial communication.

It also has the role of powering the Arduino Nano Every via USB, as it doesn't have a power jack like the Arduino Uno.

③Reset Button

You can restart the Arduino Nano Every by pressing the reset button. Use this when you want to restart the program from the beginning or when the Arduino Nano Every behaves strangely.

④I/O Port・Power

Digital I/O・PWM

Digital I/O・PWM	Explanation
D0-D19	Digital input/output(0-19) HIGH(+5V)/LOW(0V)
PWM	0 to +5V analog output Analog output by switching between 0V and +5V at high speed

PWM and serial communication are shared with digital I/O. You can specify which one to use in the program.

Unfortunately, the Arduino Nano Every has 5 PWMs, down from 6, compared to the Arduino Nano.

Analog Input

Analog Input	Explanation
A0-A7	Analog input(0-7) 10-bit A/D converter(1step change every 4.8mV)

Communication

Communication		Explanation
UART (Serial communication)	TX	Serial data transmission
〃	RX	Serial data reception
I2C	SCL	Serial clock
〃	SDA	Serial data transmission/reception
SPI	SS	Select device to control
〃	SCK	Serial clock
〃	MOSI	Master ⇒ Slave data transfer
〃	MISO	Slave ⇒ Master data transfer

Power

Power	Explanation
Vin	The voltage input to "Vin" is output. Power can also be supplied from USB port.
GND	Ground/Reference point
+5V	+5V voltage output
+3.3V	+3.3V voltage output

Other

Other	Explanation
GND	Ground/Reference point
AREF	Analog input reference voltage (0 to +5V input), Not normally used
RESET	Reset (Same function as “③Reset Button”)

⑤LED

LED	Explanation
ON	Lights up when the Arduino Nano Every is powered
TX	Blinks when sending via serial communication
RX	Blinks when receiving via serial communication
L	Connect to digital I/O No.13

Arduino Nano Every has 4 LEDs(chip parts). The “L” of LED is connected to the 13th digital I/O, and can be lighted up by setting the 13th pin to HIGH (5V) in the program.
