Heck, you could have 2,3,4 or more 1mm PCBs and make up a whole project. smiley-wink

One could solder the PCB lower on the pins so you can get to the reset button.

Edit, still, there is the option of soldering the PCB to the top if one desires.

Looks like you have a plan, I like that!

I was just going to post https://www.sparkfun.com/products/8118 and say cut these in half.

I figured thicker is more durable
Agreed.

I just wondered if there was an advantage of using the thinnest material possible or just stay with 1.6mm
292  Using Arduino / Microcontrollers / Re: 1284P top mount card on: June 22, 2014, 08:39:45 pm
Any reason to use thin 1/32" PCB material?

Reset switch not so much
You could have two pads visible  so a small screw driver short could cause reset. smiley-wink

Tell us how you are programming the bootloader (in your own words)
295  Using Arduino / Microcontrollers / Re: 1284P top mount card on: June 22, 2014, 06:45:12 pm
Not really important, but add a pad connected to GND so you can have a header pin soldered in.
For grounding scope/meter/logic probe etc.
Or
Two pads at .2"  for a loop of bare wire (I always poke my figures on a single header pin).

I can assemble them myself.

Put me down for 5 units.

Why does it matter?  (Full Swing should typically be a good safe choice for most Arduino compatible boards.)
I like the idea of full swing my self.  
IMHO, I  believe the oscillator is more stable in this mode.
It just means one has to have an entry in eg. BobuinoFullSwing in boards.txt (with low fuse set to 0xF7), which is no big problem.
Or
Use 0xF7 in Nick Gammons boot loader pgm for low order fuses for 1284.  http://gammon.com.au/Arduino/Atmega_Board_Programmer.zip
Again, thanks to you, pito and Crossroads.

@Crossroads I realize you copied and pasted the elements in the schematics, but for others C1 and 2 are 15pf and R2 is 220R.

Not sure I would do this but you could get away with 8 pins on both sides.

EDIT: On the other hand, it is nice to have the other pins there so you can clip your logic analyzer or scope to!
