The complete board is 3079 triangles  ( the base board by its self is 228 tris ) :

 

Do you have a Second Life Marketplace or would you be willing to sell your model? I still want to see what I can do but there is so much I don't know right now. This sounds like a cop-out but it will probably take me another couple of weeks working on this over my summer break.

The reason I suggested assigning the board to a vertex group was, as I had thought I had explained, so that you wouldn't have to try selecting all the boards vertices in one go (which could be tricky) so that it could then be separated to be its own object. Instead you could select some vertices > assign them to a Board vertex group, > select some more board vertices > assign these to the Board vertex group, > repeat until all the boards vertices had been assigned to the Board group. Now, to select all the boards vertices you just have to go to the Vertex Group panel > select the Board vertex group and hit the Select button at the bottom of that panel.

If you want to create a library of models, textures etc,  then you would use the new Asset Browser feature:

 

Its disappointing that for such a simple shape you have to "do some more searching to see how I can add them back."

Some options for adding back the pins :

1: Edit mode > select a pin from another component >  Shft D to make a duplicate > move duplicate to correct position and  resize if necessary. Duplicate this new pin and move to approx; correct position for the next pin. Duplicate and move for the other missing pins.

2: Create from scratch,  Edit mode select a nearby vertex > duplicate it > move , extrude etc to build up a pin. Duplicate this new pin and move to approx; correct position for the next pin. Duplicate and move for the other missing pins.

3: Edit mode, Position 3D cursor to approx correct position > Shft A  and Add a new mesh cube > resize etc........... Duplicate this new pin and move to approx; correct position for the next pin. Duplicate and move for the other missing pins.

4: Open the original Arduino model > Edit mode Select the missing pins > duplicate > P to separate to be a new object > Object mode > select the new "pins" object > Ctrl C to make a copy  > return to (or open) your new "Optimised Arduino" .blend > Object mode > Ctrl V to paste   (it should be pasted into the correct position) > Select the new "Pins" object then Shift select your partially  "Optimised " board object and use Ctrl J to join so that the pins will become part of the "Optimised" board.

Note that the exact position of pins/components will be determined when you have the top surface of the board mapped to a texture. They will need to be aligned to the solder pad positions of the texture on the board.

And you don't have to be very accurate in the dimensions of the pins. See the image below for a comparison between an actual reset switch pin relative size and the pin size in the original model.

 

The mistake that you made at the very beginning is that you should have made a copy of your original Arduino .blend file using the Save as option, then in this new file Object mode > Shft D to make a duplicate copy of the original board and worked on simplifying this copy. Doing it this way means you would still have the original board in the same .blend as your simplified board which would have been useful for when you make errors like this (deleting parts by mistake) You could easily copy and paste from original to simplified model.

Nothing to stop you now copying and pasting a copy of the original board object into this new file:

 

I had hoped to maybe take a Blender class this summer (wanted a class that aligns with making things like the Arduino, DC Motor, etc). I am sure there are many gaps in my understanding. I am self-taught and of course this makes it ineffective and I ask a lot of questions. Also, I use Blender sporadically so I need to be reminded of things that I saw before. My object is really to build things that I can use in Second Life for teaching.

A while back I stumbled across a great article - Engineering Education Island: Teaching Engineering in Virtual Worlds and asked the author for suggestions because I wanted to build a virtual learning environment for my school. He said that they had stopped using SL because of the cost increase back in 2012 or so. Many educators left SL at that time. I recently did a survey and found that only 15% of the educational sites listed on the https://wiki.secondlife.com/wiki/Second_Life_Education_Directory still have some sort of presence in SL. That is a tremendous decline. 

My end goal is to build a virtual cleanroom. I have Maya models for much of the equipment and will be going to UNM to get the rest of the info to build the cleanroom this summer. In the mean time I am attempting to learn as much as I can and create course content that I can use in my engineering classes.

I wanted to thank everyone for their help and your suggestions. It is much appreciated.

I have to work on some lower LoDs first. When done I will and send you a copy inworld along with a note card with a link to the .blend, probably Monday.

Thank you so much. I received the models (three of them) and two textures file but didn't see the notecard for the location of the blend file. Thank you so much for all of your help, this is awesome!

To close the Arduino chapter of this thread , the lower LoDs :

 

Using the LoDs above :

Board size approx. :  1.5m x 2m   =  LI 1

                                     2m x 3.2m   =  LI 2

                                    4m x 6m       =  LI 6

Hello

It has bee a little while since I used Blender last. I wanted to use some of the STL files that my students created in Solidworks and convert them in Blender. I believe this was the primary reason why I had to use Blender. Anyway, if I have a model that has been scaled in Blender how do apply the scaling to get the scale back to 1?

Thanks

I figured it out, thanks

Hello again,

Got a question for you about models that have already been uploaded. Is there a way to review the Physics info for the model?

Thanks

If by review you mean to change/edit the physics model of the mesh asset, then that is a no.
