Bombsighted Arduino Mega Layout

Page history last edited by MrTundraMan 11 years, 7 months ago

I have looked around long and hard for a page which nicely describes the Arduino Mega connector/hole locations. They all suggest using the Eagle files for the card on the arduino site. I did that and created the following mark-up:

 

 

I hope this proves to be useful to other people.

 

A few notes

 

  1. Dimensions are in 1/1000's of an inch. For instance, the hole at (600,100) is at 0.6 inches to the right and up 0.1 inches.
  2. Based on what I have read in various places, I believe that the pin at (950, 2000) really should be at (940, 2000). Some things I have read make me think it's really at (935).
  3. You may have to do some math if your CAD program puts 0,0 at the top left (as ExpressPCB does).
  4. You may have to do even more math if your shield is offset (bigger than the shield above). For me, I put my shield at the corner and then move it later inside the board footprint.
  5. This layout should work fine for other Arduinos, such as the UNO although I haven't included the mounting hole bombsights for those cards.
  6. This may be done wrong. Check to make sure it is right. I print out a 1:1 and put it on top of the Mega processor board to check for stupid errors.
