Prepare the header strip:Cut the strip to length if necessary. It will be easier to solder if you insert it into a breadboard - long pins down
Add the breakout board:Place the breakout board over the pins so that the short pins poke through the breakout pads
And Solder!Be sure to solder all pins for reliable electrical contact.
Solder the longer power/data strip first
