Description:
Arduino NANO with ATmega328 Microcontroller is an ultra-low size Arduino board with AVR architecture and based on Atmel Atmega328P-AU microcontroller, which includes all capabilities of Arduino Duemilanove except DC power jack in the smallest size.
This miniature board is like an Arduino UNO type, but with a smaller size, which is suitable for a flyer and tiny robot. This Arduino is idealized for breadboard working too.
The Arduino NANO is equipped with 8 pins for analog inputs (to run 10-bit resolution means 1024 different values), and 14 digital IO pins that 6 pins can be used for PWM outputs, 2pins for serial receive and transmit data, 2pins for external interrupts, 4pins for SPI serial ports, and on for LED indicator. It also has a pin for reference voltage input for analog reference comparison and one pin for reset the microcontroller.
This Arduino chip operates with a TTL logic level of 3.3V DC and can be supplied with a recommended voltage of 7V to 9V DC. It can easily be supplied through a micro-USB to USB cable from any USB port or through the AC to DC or a 9V battery. It is also compatible with 1.0 Arduino pinout and any shields with 3.3V DC.
Arduino NANO can withstand maximum input and output voltage of 3.3V, which means that applying more than 3.3V DC to any input or output pins may damage the board. This board has all the requirements of the microcontroller support.
Arduino is an open-source platform based on simple userfriendly hardware and software.
The Arduino board can be employed as a slave operator, that performs simple digit works based on instructions.

KEY:. Input pin, internal pulldown This foot high, clear the record for the host address from the machine.
PIO: extended functionality for setting the module master-slave mode, the default internal pull-up resistor from the machine; external 1K pull-down resistor connected to ground, as the host. Currently only supports 9600bps communication, does not support the AT commands. Host, when pass-through traffic from the machine, there must be a certain time interval between packets. For example, the packet length is 500 bytes, then the transmission time interval between packets can be set to no less than 600ms. Otherwise, you may lose data.

This module uses the newest 2.4ghz transceiver from Nordic Semiconductor, the nrf24l01+. It integrates a complete 2.4ghz RF transceiver, RF synthesizer, and baseband logic including the Enhanced shockburst™ hardware protocol accelerator supporting a high-speed SPI interface for the application controller. The ‘+’ version of the IC has improved range, sensitivity, and data rates. The command set is backward compatible with the original nrf24l01.Worldwide 2.4GHz ISM band operation 250kbps, 1Mbps and 2Mbps on air data rates Ultra low power operation Power supply : 1.9~3.6V Dimension : 12x18mm
