I've downloaded Arduino Pro Micro library but can't create board layout with added component (Eagle Lite)

Layer 20 (dimension) shows the outline of the board. The 100x80mm

limitation starts at the origin (0,0). If your board is offset from the

origin it's possible that you're outside of the limit.

Thanks for the reply, just looking at layers and they start at layer 90

and end at layer 254. How do I select layer 20?

Thanks again, regards Steve

Hi, Thanks for the reply, I've found layer 20 and can now see the boundaries of the board area but the board area seems to be taken up by all of the Arduino Pro Micro layout, however the physical size of the Pro Micro is only 30mm x 15mm. I'm puzzled to why such a small board seams to take up all the 100mm x 80mm dimensions. I downloaded the Arduino Pro Micro library from Element14.

Any ideas, why I'm not seeing the Arduino as a smaller component within the 100mm x 80mm build area?

Regards Steve

Post a screenshot or two, it'll make it a lot easier to see what you're

referring to.

Screen shot below, the frame for the board limits seem to be from the bottom left of the Arduino board but I can't get the outline of the limits of the board (100mm x 80mm) to display. I've realised I can move my components to the right of the Arduino so I'm guessing the board limits are working just not showing. My other problem is I don't seem to be able to rotate the group of components making up the arduino board. Any ideas?

Thanks for your help

Think I'm getting there I used the wire tool to draw a rectangular limit to the board size max of Eagle Lite the place my compost accordingly, I still can't rotate the arduino component though so any guidance would be appreciated.

Thanks in advance

Well, first, there should normally be an outline of the allowed area in

layer 20 when you first create a board. Eagle does this specifically to

help with what you're currently going through. However, you've got past

that now, so...

You won't be able to rotate the arduino in situ if its bottom left

corner is at the origin. To do so would put some of the pins outside the

valid area to the left. Instead, you should MOVE it. Drag it away into

the free space above and to the right, then right-click to rotate it

while moving. Now place it somewhere completely within your blue box and

it should work.

Any ideas, how I get the outline of the permited board area to display? I've also got problems with one air wire, I've tracked it down to none terminated pins on a couple on connectors, how do I terminate these pins, i.e. let the eagle know they have no purpose in the circuit ?

thanks in advance

There's nothing magic about the outline, it's just a line drawn in the

Dimension layer. Eagle puts it there when you create a new board, but

after that it's just a line.

You don't need to. Well, you might, in some cases, need something on a

pin to avoid an ERC warning or error, but not for a connector pin. In

fact the only cases that should produce errors are ones where your

circuit probably needs something connected there. Any others are library

bugs.

What problem are you having with this airwire? Have you tried RATSNEST

to re-calculate? If it doesn't correspond to an active, unrouted net,

that should remove it.

I've had one air wire for ages, I found an un routed net and corrected it, re did autorouter and RATSNEST but it didn't resolve the problem so I deliberately added an un routed net to check RATSNEST was working. As I thought it would, it now reported two air wires. I un did the deliberate un routed net and now I have two air wires. Both I now suspect are not there but eagle is not refreshing. Any ideas ho I can  resolve the air wires issue. I now suspect both air wire are not present.

thanks

Steve
