Arduino nano pinout diagram3/5/2023 External Interrupt Pins 2 and 3: These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value.They are connected with the corresponding ATmega328P USB to TTL serial chip. Serial Pins 0 (Rx) and 1 (Tx): Rx and Tx pins are used to receive and transmit TTL serial data.Out of these 14 pins, some pins have specific functions as listed below: Internal pull-up resistor of 20-50 KOhms which are disconnected by default. Each pin operate at 5Volt and can provide or receive a maximum of 40mA current, and has an The 14 digital input/output pins can be used as input or output pins by using pinMode(), digitalRead() and digitalWrite() functions in arduino programming. +5V Pin: If you have a regulated +5V supply then you can directly provide this o the +5Volt pin of the Arduino.The on-board voltage regulator regulates it to +5V. Vin Pin: The Vin pin can be supplied with an unregulated 6-12Volt to power the board.USB Jack: Connect the mini USB jack to a phone charger or computer through a cable and it will draw power required for the board to function.There are total three ways by which you can power your Nano. This board especially is breadboard friendly, and that's why it is very easy to handle the connections. The Arduino board is designed in such a way that it is very easy for beginners to get started with microcontrollers. Other Development BoardsĮSP32 Understanding Arduino Development Board Note: More technical information can be found in the Arduino Nano (v2.3) Datasheet linked at the bottom of this page. To provide reference voltage for input voltage.Īrduino Nano Internal Specifications Microcontroller Used to receive and transmit TTL serial data. Used to provide analog input in the range of 0-5V Vin: Input voltage to Arduino when using an external power source (6-12 Volt).ĥV: Regulated power supply used to power microcontroller and other components on the board.ģ.3V: 3.3Volt supply generated by on-board voltage regulator. Arduino Nano Microcontroller Board Pinout Configuration # So let's see the Arduino Nano microcontroller development board pinout and The pin configuration. They use the same Processor (Atmega328p) and hence they both can share the same program. The Arduino Nano is another popular Arduino development board very much similar to the Arduino UNO. Arduino Nano is also popular microcontroller development board Based on 8-bit ATmega328P microcontroller.
