Step 6Solder
Please refer to the pictures below for placement of parts. I can offer a more detailed diagram if anyone is interested.
Note that there are 2 red lines on the Eagle .brd file. These are power traces and need jumper wires placed where the red lines are.
I started by soldering the stackable headers first (center headers, then inside, then outside), since they are slightly harder to access with the soldering iron.
The 3 holes next to the IC are for the 16mHz resonator and it can go in either way (middle pin is ground, so it doesn't matter)
Then I add the female headers. Next the male pin headers. It is helpful to install these with a jumper holding them to an adjacent header pin, so you don't have to hold them while soldering.
Power LED and resistor next, then the 28-pin socket and power screw-terminals.
Then the 10k pull-up resistor for the reset button as well as the button.
Remember the 2 jumper wires.
There are not that many parts on this board and other than the capacitors and power LED, you don't have to worry about polarity while placing the components (you need to plug the IC's in correctly when you are done, but the sockets can go in either way).
Remember, when soldering, to heat the contacts and let the solder melt onto it. If you try to heat the solder directly, you might end up with a big mess.
