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.

Product description
Package contents:
1 x Load cell 0-5KG
1 x HX711 24BIT Precision ADC Module on breakout board
10 x Breakaway header pins for HX711 connection
Everything you need to take accurate force measurements with and Arduino, Raspberry Pi, or other microcontroller in one complete package!

Information:
Load cell - Sturdy aluminum alloy construction. Strain gauges pre-attached with strain relieved wires. Accurately measures forces from 0-5kg (0-11 lb).
HX711 - This top of the line load cell amplifier mounted on a breakout board pairs perfectly with the load cell to provide fast, accurate force measurements. It measures small changes in the resistance of the strain gauges mounted to the load cell and passes these values directly to any microcontroller (like an Arduino or Raspberry Pi).
Load cell specs:
-Wire leads pre-attached, 22 cm (8.5 in) long
-Dimensions 12.7 mm high, 12.7 mm wide, 80 mm long (0.5 in x 0.5 in x 3.15 in)
-4 mounting holes, 15 mm spacing on each side. One side both holes tapped M4 thread, the other side both holes tapped M5 thread.

HX711 specs:
-Operation Voltage: 2.7V–5V
-Operation Current: < 1.5mA
-Mounted on breakout board
-Includes breakaway headers for connection, soldering required
