To connect the analog devices the Arduino Nano provides its user with 8 analog pins that have a 10 bit data resolution. For further clearance we have highlighted the digital pins of Arduino Nano as in the image below: Similarly, there are 6 PWM pins that are D3, D5, D6, D9, D10, D11 and the duty cycle ranges from 0 to 255.įor SPI (Serial Peripheral Interface) communication protocol you can use the digital pins D11 to D13 for COPI, CIPO and SCK.
To power up the devices connected with Arduino Nanoĭ2 to D13 (D11 for COPI, D12 for CIPO D13 for SCK)įor connecting digital devices with Arduino Nanoįor connecting the analog devices Arduino Nanoįurther we also explained the pins according to the categories we made in the above table Digital Pins of the Arduino Nanoįor the devices that have digital input and output and are to be connected to Arduino Nano there are 14 pins in which 2 pins are data sending and receiving pins that are TX and RX pins. Moreover, for SPI communication protocol you can use D11, D12, D13 for COPI (controller out, peripheral in), CIPO (controller in, peripheral out) and SCK.įor user understanding we have divided the pins of Arduino Nano into different categories and based on these categories we have made a table that is given below that demonstrates the pinout of the Arduino Nano. Among the 36 pins 6 pins are for the ICSP (In Circuit System Programming), 14 digital input and output pins, 8 pins for powering the devices, 8 analog input and output pins and lastly there are two pins for data receiving and transmission.įor the TWI communication protocol there are SCL, and SDA pins required and for that purpose pins A5 and A4 are used. Since this is a small size board it comes with a limited number of 36 pins that can be used for various purposes. To power up the Arduino Nano it requires 5 volts and 40 mA current and that can be provided by either the USB port or the Vin pin of the Arduino Nano. This controller is equipped with a clock speed of 16 MHz and has a flash memory of 32 kilobytes along with static RAM of 2 kilobytes and EEPROM of 1 kilobyte. Like other Arduino boards the Arduino Nano also comes with the AVR microcontroller of ATMEL family having a model name ATmega328P. Technical specifications of the Arduino Nano One of the Arduino boards is the Arduino Nano that is handy because of its small size, so we have explained the technical specifications along with the pinout of the Arduino Nano in this tutorial. To use any of the Arduino boards one should have knowledge of technical specifications and pinouts of that specific board. The Arduino is a platform that provides its users with a wide variety of microcontroller boards that can be used in various projects.
