  • Arduino Nano Revision 3 Development Board

    Arduino Nano Revision 3 Development Board

    Arduino compatible board with the ATMEGA328P microcontroller

    The Arduino Nano is a small, breadboard-friendly version of the Arduino UNO.

    It has the same functionality as the Arduino Duemilanove but at a much smaller size.

    The Arduino Nano is well suited for rapid prototyping and as a great general-purpose microcontroller. 

    Since Arduino is open source hardware & software, anyone can copy the Arduino Nano boards exactly, even using original parts.

    We are therefore able to supply this Arduino identical compatible board at a fraction of the cost of the original.

    Key Features

    Variable Input Voltage (7-12V)

    Indicator LEDs for immediate feedback

    Compact Form Factor (45mm x 19mm)

    14 Digital I/O pins

    8 Analog I/O pins

    16 MHz clock speed

    32kb flash memory (of which 2kb is used by the bootloader)

Ultrasonic ranging module for Arduino and other microcontroller projects

 
This is a module with a 40kHz ultrasonic transmitter / receiver pair mounted on the front of a small PCB, with the required control circuitry on the back.
It sends a short 40kHz square wave ou, timing how long it takes to return to the module, You can calculate the distance it has traveled via the speed of sound.
 
Voltage : 5VDC
Working Range : 20mm to 4500mm
Accuracy : 2mm
