Construction and connection precautions

power supply
VCC is directly connected to the pins of the microcontroller, connecting voltages higher than 5V may permanently damage the chip.
input Output
The Arduino Pro has 14 digital input/output (I/O).
Each pin is allowed to draw up to 40mA of current, which allows direct connection of LEDs with resistors and control of other integrated circuits.
In addition to standard I/O, some outputs have special functions.
With the help of a free environment provided by the manufacturer, software can be created and uploaded.
You can use the PL2303 programmer


The Nano version, like the Pro version, is based on popular modules
It has a LGT8F328P microcontroller which is compatible with MEGA328P

32kB Flash
2kB SRAM memory
E2PROM 0K/1K/2K/4K/8K (flash shared)
It is clocked with a 16 MHz clock signal.

The board has pins – output/input

16 digital pins – can be used as input or output. The pins operate on the 3.3V TTL standard. They are each rated at 40mA, and they also have built-in pull-up resistors. Some pins have additional functions (UART, INT, PWM, SPI, LED), including 8 PWM channels, e.g. for controlling servos/motors, e.g. SG-90 Servo TowerPro
6 analog inputs, each supporting measurements with 10-bit resolution. Some pins have additional functions (I²C, AREF, reset).

Arduino Nano can be powered

Via Micro-USB cable
from a regulated voltage source of 3.3V.
Via 5V connector
Programmers that provide communication with a computer can only be powered via USB.

The board establishes a communication system with the computer by:

UART interface – based on pins 0 (RX) and 1 (TX).
USB – Layout
Also supports I²C (TWI) and SPI interfaces

For 3.3/5V voltage, jumper selection.
for manual reset
LED switch to control the operation of the system
Connectors arranged on the board allow you to connect the board directly to the contact pad.
This version has for welding
The programming of the connectors is done using the Arduino IDE, which is very beginner friendly free software. – IDE program – http://www.arduino.cc/en/Main/Software
The microcontroller on the board has a preinstalled bootloader that allows you to upload software without using additional hardware.
As standard, the module includes the BLINK LED 13 program and bootloader
. In addition, the processor can be programmed through ICSP.
The chip program can be encrypted with a custom GUID (unique identifier)
