1. Introduction
This Arduino NANO development board is different from the common NANO development boards on the market, it retains the same power supply design as the official version, does not make any performance cut, adopts the same layout and power supply design as the official version, and has the same quality and stability as the official version, but the price is consistent with the common cut version, and even one-tenth of the official version.Arduino NANO is widely loved by makers due to its low price, and with the help of a breadboard or a dedicated expansion board, it has almost the same performance and expandability as the Arduino UNO R3.

5, Development board decoding

Reset button
Press the reset button and run the program again.USB serial port chip
This chip is responsible for converting the data received from USB into serial data for the main control chip.3.3V/5V power supply module
The power module is responsible for the power supply service of the motherboard, the 6-12V power supply from the external access is stepped down to 5V/2A/10W output, and can drive multiple servos, toy motors, miniature slides and other devices.USB interface
responsible for data download and USB power supply.ATMEGA328P microcontroller chip
The ATMEGA328P microcontroller is the brain of the development board, responsible for program storage, execution, calculation processing, signal input and output, and other functions.ICSP serial data interface
Connect this interface when writing the initialization program to the development board or using the compiler to download the program.Crystal oscillator
Provide clock signal for ATMEGA328P microcontroller.LED indicator light
The board is equipped with 4 LED indicators, (ON) is the power indicator, it lights up when powered on, (RX)(TX) are serial port signal indicators, the LED lights blink when there is serial port communication, (L) is the D13 pin indicator light, the light is on when the D13 signal is high.
