I cannot find the specific distance between the ICSP pins, placed central on the board, towards the pins of on eighter side of the Arduino Mega.
On eighter side there is the D0 and A5 respectfully.
I’m having a hard time finding the right distance to create my Shield.
Does anyone have this distances?
Or even a schematic with all the measurements?
Ok, the information is readily available, but for non native english speaking person finding right keywords can be more difficult and "footprint" sounds something very much different from technical dimensioned drawing.
And footprint is is usual term for how are pins placed and what place parts occupy, at least in KiCad, which is SW for making PBC (and before in Eagle) and probabely in majority of others similar products, as wel as in PBC manufacturers, as well as on many forums.
Try to search forum here for footprint and you will get lot of threads with this word in title and many more with it in body.
All connectors on the board, with the exception of the header that starts with digital pin 8 and ends with SCL, are on a 2.54mm / 0.10" grid. Unfortunately the spacing between digital pin 7 and digital pin 8 is 0.160", a very non-standard amount that originated from an error with the early UNO board.
Coincidentaly, in my occupation we have maps that point out the trajectory of cables.
That is called footprint as well. The icon is two feet on a circle. Me, thinking in pictures, visualizing it has someting to do with feet, on a map, and walking from point to point.
Feet, in relation to a PCB, would be unlogical in my case. Nevertheless… yeah footprint is logical if one leaves out the feet thingy.
