Prepare the header strip:

Cut two strips to length if necessary. It will be easier to solder if you insert it into a breadboard - long pins down

Add the board:

Place the board over the pins so that the short pins poke through the pads

And Solder!

Be sure to solder all pins for reliable electrical contact.

Solder one side of the board at first

(For tips on soldering, be sure to check out our Guide to Excellent Soldering).

Flip the breadboard around to solder the other strip

You're done! Check your solder joints visually and enjoy!
