Pins Description of Arduino NANO RP 2040 Board

Power Pins

1. Vin

This pin is used for supplying an input voltage of 5 volts. The input voltage is a direct current supply voltage. The input voltage is used to regulate the integrated circuits which are used in the connections. When this pin is in use the USB pin is disconnected. Vin is also known as the primary voltage source on the Arduino NANO RP 2040 board.

2. 5v pin

The 5v pin is used as the output for external components. The output is 5v. This pin is used only when the board is powered by USB or the power source of the 5v pin is a USB connector.

3. 3V3 Pin

The 3V3 pin is used as an output pin. This pin generates an output voltage of 3.3 volts.

4. Reset Pin

The RESET pin is used to reset the board. For resetting the board we have to pull down this pin to LOW.

5. GND pin

This pin is used as the ground pin of the board. 

Digital Pins

1. Digital I/O Pins

There are a total of 22 digital input/output pins available on the Arduino MKR NB 1500. The digital pins are used as an input or output according to the requirement. The digital pins are only able to read two values which are:-

1. High
2. Low 

However, we can use 1 for the high state and 0 for the low state. When these pins receive 0V they are in a LOW state and when they receive 5V they are in a HIGH state.

The digital pins on the Arduino MKR NB 1500  are from D0 to D21

Analog Pins

There are a total of 7 analog pins available on the Arduino NANO RP 2040 board. Analog Input Pins are used to take the signal from analog sensors and then convert it into a digital value. These pins can receive any value, unlike digital pins. It can receive value not only in the high or low states but in other forms also. The analog pins of the board are from Pin A0 to Pin A06. 

The Analog pins of the Arduino NANO RP 2040 Board are as follows:-

PWM Pins

There are 20 pins also known as Pulse Width Modulation pins. The work of these PWM pins is to convert the digital inputs to analog output. These pins provide 8-bit PWM output with the analogWrite () function. The PWM pins of the Arduino NANO RP 2040 board are 0,1,2,3,4,5,6,7,8,10,11,12,13,14,A1,A2,A3, A4, and A5.

Communication Pins of Arduino NANO RP 2040

1. I2C Pins

The Arduino NANO RP 2040 board contains the I2C communication protocol. It stands for “Inter-Integrated Circuit.” It is a two-wire serial communication protocol. It uses two pins for communication purposes. One of them is used to send data while the other pin is used to receive data. 

The two pins of the I2C protocol are “Serial Clock Pin(SCL)” and “Serial Data Pin(SDA)”.

• SCL – It is defined as the line or pin which transfers the clock data. SCL pin is used to synchronize the shift of data between two devices. This signal is generated by the master device.

It is a clock line.

• SDA – It is defined as the line or pin which is used by slave devices to send and receive data. It is a data line.

I2C pins on the board are A4 which is SDA and A5 which is SCL.

2. SPI Pins

The Arduino NANO RP 2040 board supports the “Semi – Peripheral Communication Protocol” or SPI. The SPI protocol is used to develop communication between the controller device and its peripheral devices. Three pins are needed for SPI communication protocol which are:- 

• MISO – It stands for Master Input/Slave Output. This data line sends data to the master device. 
• MOSI – It stands for Master Output/Slave Input. This data line is used for sending data to slaves/peripheral devices.
• SCK – This pin is used to synchronize the data transfer between the master and slave device.

SPI pins on the board are D11 which is used as the MOSI pin, D12 which is used as the MISO pin, and  D13 which is used as the SCK pin.

The Pins MISO and MOSI are also known as CIPO and COPI which stand for “Controller In Peripheral Out” and “Controller Out Peripheral In” respectively.

3. UART Pin

The Arduino NANO RP 2040 consists of a UART communication protocol which is used for serial communication of data. It needs two pins for communication purposes which are Rx and TX.

• Rx – This pin is used to transmit the serial data.
• TX – This pin is used to receive the serial data.

UART pins on the board are D1 which acts as RX pin and D0 which act as TX pin.

AREF

The AREF pin is used to provide the external reference voltage to the analog pins for the analog-to-digital conversion process.
