An easy way to line up the Arduino headers for soldering is to plug them into an Arduino, then place the shield upside-down on top of them, as shown in the picture below. Be careful to insert the header pins into the correct set of holes before you begin soldering. '''Note:''' if you use this alignment technique, make sure your soldering iron temperature is not excessively hot and avoid holding the iron on a single pin for more than a few seconds as this could melt the Arduino’s female headers. | An easy way to line up the Arduino headers for soldering is to plug them into an Arduino, then place the shield upside-down on top of them, as shown in the picture below.
