Assembling the Dragon Rider 500 for use with the AVR Dragon

Step 9 Pin Headers Part II

Now that the sockets have been installed we can continue with the remainder of the pin headers. Now is a good time to install the headers because right now they are the components that stick up the most on the board. this means that setting the Dragon Rider upside down on a flat, level surface will aid in the alignment of the headers. You will find a full list of the headers installed in the this step, as well as the packages they come from, at the bottom.

1. Place and solder the 2x5 pin headers.
2. Break the single-row pin headers to the appropriate length as was done in step 7.

• For J22-24 use a 1x3 pin header leaving the hole to the right of each empty for now.

3. Place single-row headers and tack one pin of each with solder.
4. Check that the headers are flush to the board and vertical. If not, straighten by heating the pin while moving the header with your finger as was done in step 7.
5. Solder the remaining pins of the pin headers.
6. Finish J22-J24

• Break off 3 single-pins for use with J22-J24
• Place single pins in the available holes and insert a shunt to hold them while you solder.
• Solder the pin to the Dragon Rider PCB

Note: Later on I decided to install a 1x3 header in J34 so that I had the ability to select where the Serial add-on draws power from. This is completely up to you but you might want to read the rest of the instructable before you continue assembly.
