Hello,
I am trying to design the arduino promini part to solder it to a pcb board. I tried to find the foot print online but could not find it.
Can anyone help me with the foot print of promini?
Thanks
There are so many versions out there it may be best to get callipers and do the measurements yourself.
There three types I have are all on 1/10 inch grids.
.
Two rows of 12 pins on 0.1" centers, 0.6 apart? Doesn't seem all that hard.
Can also get the free version of Eagle from http://www.cadsoftusa.com/ and open the .brd file
and open the .brd filehttps://www.arduino.cc/en/Main/ArduinoBoardProMini
I wanted to get the distance of I2C pins (A4,A5,A6,A7 ) Pins from the row. Couldnt find any information regarding this.
Thank you for the links, I ll have a look at them.
Hello,
I am not able to open those links.
Could you provide me with Any information on the distance /position of A4,A5,A6,A7 pins?
Thank you
Show an image of the mini that you have.
.
A4-5 and A6-7 are 1/10 inch from the outside row and offset by 1/20 inch
Hello,
Thank you so much for your reply.
Could you please tell me the the distance of the horizontal row from the vertical rows if possible.
Thanks again
RAW and GRN are 1/10"
Thanks a lot.
I really appreciate your help.
buy them from one supplier. I would offer that I have at least three different layouts, some with pads on both ends, some with two rows of pads on one end, some like yours.
also, the pads on the ends are not lined up on the same centers as the two main rows.

I do not believe that is correct.
the pins on the end of the board are spaced on 0.1" centers.
open in PAINT, copy those pins, then drag to be over any A3 and confirm the location.
Using that highly technical drawing program PAINT, the holes are not centered between A2/A3 and Vcc, but are off a bit.
I am using Ubuntu and there is nothing approaching the quality of PAINT for Linux or I would post results.
not sure if this will upload.....
I coped the pads from the end of the board to keep the same spacing.
then overlaid, lining them up with the main pads. you can see how the inner pads are not on the same spacing.
I laid in two lines to show that the inner pads are also not centered.
here are some of the variants. see the pins at the ends of the boards. some centered, some off center, some double row. my suggestion is to buy them from a place like SparkFun who have their own boards made for them, based on the same layout. if you buy from China, buy in bulk. they layout can change at any time.
compare to your board. none of these have A6/A7 next to the CPU
If I remember correctly, the Pro-Mini was pin compatible with the BasicStamp. the BasicStamp was the leader in this area for boards of this size and capability. that showed that free software would create a huge groundswell of support and users. The Arduino took that to a new level with free software, lower costs and more capability.
Hello,
I bought afew from adafruit.
Could you please provide me with the footprint which suit this?
Thank you.

I did not use the supplied image, I used an actual board I had and measured with callipers.
If OPs PCB is different than my PCB, the OP must measure their's with callipers.
One thing for sure, if you have 10 different manufacturers you will have 10 different board dimentions.

there is a link to the eagle files
