Topic: Pin spacing dimensions / prototype PCB manufacturers? (Read 3158 times) previous topic - next topic



I'm hoping to create my own shield for my quadcopter project and get a prototype PCB board made.

I was wondering if someone might be able to point me towards a resource that gives the dimensions of the spacing between the two rows of pins on the Arduino Uno please? Also, the spacing between the individual pins would be very useful to know.

If anyone happens to know any companies that manufacture single PCBs that would be very useful :)


The Eagle files for all of the Arduino models are linked from their respective pages in the Hardware section.

Basically you just want to grab the files for the (e.g.) Uno, strip off all the parts except the pin headers, and then go from there.

batchpcb.com is fairly inexpensive for single boards.


Thanks Chagrin :) Looks like i'll be downloading and having a play with the freeware version of Eagle this afternoon.


Sparkfun's Eagle library has an Arduino shield component.  Makes it easy to create a shield with it as a basis.

Hi Whitworth,
Thats correct. All the info you need is avail on the Arduino web site. But you can also use a free software by Express PCB and design your own boards. From their component manager, you can select the pin header you want.
This comapny lets you have 3 prototype boards for $51.00 US. plus shipping. They do a great job and have real fast turn times. I made my own PC boards like you did and I was able to get 6 boards for $51.00.
The way you do this is by using their standard size board, which is 3.8 x 2.5 inches and put 2 circuit on the board. Use the device manager to put a set of holes down the middle of the board and you can snap the board in 2 and thus have 2 boards. If your circuit is small enough you can get 3 on the board.
I'm making my own "UNO" boards now and they work great. I use a socket to remove the Atmega chip and use the original UNO board for the programming.
Here's a link to the PC Board company as well. Good luck
