Arduino UNO is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header and a reset button.

Arduino Dimensions,hole Patterns and How to Fasten: As picture show,all arduino mounting holes are 3.2mm-about 0.125"-in diameter.they will accomodate M3-0.5 or UNC 4-40 screws and standoffs.so if i want to fasten the pcb with a plastic box or other case?

Apr 7, 2015 · What are the dimensions of the original Arduino Uno R3 package box? Are you referring to the Arduino's size? Or, are you referring to the box that some vendor shipped it in? The Arduino size can be measured. The box size depends on the vendor. You shouldn't have thrown the box away.

Jun 20, 2011 · hello! i have found the overall dimensions of the arduino uno board, but can someone tell me the hole pattern and spacing? i do not have the board in hand yet, and am trying to design a mount for it on my project.

Sample sketches for the UNO R3 can be found either in the “Examples” menu in the Arduino IDE or in the “Documentation” section of the Arduino website [4].

Dec 25, 2013 · The physical dimensions of the Uno need only be rough, the heights of shields vary substantially, and that may be only part of the height problem. The other part is what plugs into it.

Arduino Uno Dimensions tell you how big the board is in terms of millimeters but you can't really tell how small it is. So here's a picture of my dusty, trusty Arduino Uno R3 (clone) in my hand:

Description The Arduino® UNO R3 is the perfect board to get familiar with electronics and coding. This versatile development board is equipped with the well-known ATmega328P and the …

Recently I was busy building a nice case for an Arduino and I needed the dimensions to make the correct mounting holes. I found this handy diagram online and though I would share it with everyone. UPDATE: Here are some more drawings that include the pin layouts as well. We recommend the following books:
