The PWM signal can be generated using analogWrite () function. PWM Pins Pins - 6, 8, 9, 12, 13, and 14Įach of these digital pins provide a Pulse Width Modulation signal of 8-bit resolution. The board also has a micro USB connection port, a reset button, an ICSP. Thông thng, chng trình b np khi ng Arduino c s dng lp trình bo mch Arduino. The pins RX and TX are connected to the corresponding pins of the USB-to-TTL Serial chip. Now, let us study the pinout of an Arduino Nano and the description of each pin. ICSP là vit tt ca In Circuit Serial Programming, i din cho mt trong nhng phng pháp có sn lp trình bo mch Arduino. ![]() These two pins RX- receive and TX- transmit are used for TTL serial data communication. Serial Communication Pins Pins - 1, 2 1 - RX and 2 - TX Arduino Nano Features ATmega328P Microcontroller is from 8-bit AVR family Operating voltage is 5V Input voltage (Vin) is 7V to 12V Input/Output Pins are 22. To provide a reference voltage for input voltage. Used to receive and transmit TTL serial data.ġ0 (SS), 11 (MOSI), 12 (MISO) and 13 (SCK) Used to measure analog voltage in the range of 0-5VĬan be used as input or output pins. Vin: Input voltage to Arduino when using an external power source (6-12V).ĥV: Regulated power supply used to power microcontroller and other components on the board.ģ.3V: 3.3V supply generated by on-board voltage regulator. The ICSP pinout for Arduino Nano is shown in Figure 2. The Nano, like all Dual-Inline Package (DIP) modules, has its physical pins numbered in a U shape, from top left to bottom left, to bottom right to top right. Digital pins: There are fourteen pins that are used for the Digital inputs/outputs and are labeled as D0 to D13, where some digital pins are used. Arduino Nano board contains thirty pins that are used for different purposes, and this usage of the pins is explained in detail in the next sections. Arduino Nano Pinout Configuration Pin Category The ICSP interface is used to program Atmel controllers on which the Arduino module is assembled. What is the pinout configuration of Arduino Nano.
