Start by preparing the header strip, cut to length if necessary. It will be easier to solder if you insert it into a breadboard - long pins down.
Add the ADT7410:
Place the board over the pins so that the short pins poke through the top of the breakout pads
Be sure to solder all pins for reliable electrical contact.
OK, you're done!
You can now plug in your ADT7410 breakout and enjoy using this high precision and high resolution temperature sensor.
